}).await?;
|
|
```
|
|
|
|
### Performance Metrics
|
|
|
|
```rust
|
|
use core::events::*;
|
|
|
|
// Event-driven metrics collection
|
|
let mut event_processor = EventProcessor::new(EventProcessorConfig::production());
|
|
|
|
// Record performance events
|
|
event_processor.record_event(TradingEvent {
|
|
event_type: EventType::OrderLatency,
|
|
timestamp: Timestamp::now(),
|
|
metadata: hashmap!{
|
|
"symbol".to_string() => "EURUSD".to_string(),
|
|
"latency_us".to_string() => "23".to_string(),
|
|
},
|
|
});
|
|
|
|
// Get aggregated metrics
|
|
let metrics_snapshot = event_processor.get_metrics_snapshot();
|
|
println!("Events processed: {}", metrics_snapshot.total_events);
|
|
println!("Average processing time: {}μs", metrics_snapshot.avg_processing_time_us);
|
|
println!("Error rate: {:.2}%", metrics_snapshot.error_rate * 100.0);
|
|
|
|
// Export metrics for Prometheus
|
|
let prometheus_metrics = event_processor.export_prometheus_metrics();
|
|
```
|
|
|
|
### Buffer Management
|
|
|
|
```rust
|
|
use core::events::*;
|
|
|
|
// High-performance event buffering
|
|
let buffer_manager = BufferManager::new(8192); // 8K events capacity
|
|
|
|
// Write events with ultra-low latency
|
|
let event = TradingEvent::new(EventType::MarketData, "EURUSD", serde_json::Value::Null);
|
|
buffer_manager.write_event(event)?;
|
|
|
|
// Batch read for efficiency
|
|
let events = buffer_manager.read_batch(256)?; // Read up to 256 events
|
|
for event in events {
|
|
process_event(&event).await?;
|
|
}
|
|
|
|
// Monitor buffer performance
|
|
let buffer_stats = buffer_manager.get_stats();
|
|
if buffer_stats.utilization > 0.8 {
|
|
println!("Warning: Event buffer utilization high: {:.1}%", buffer_stats.utilization * 100.0);
|
|
}
|
|
```
|
|
|
|
## Security & Authentication APIs
|
|
|
|
### JWT Authentication
|
|
|
|
```rust
|
|
use tli::auth::*;
|
|
|
|
// Generate JWT token
|
|
let token_payload = TokenPayload {
|
|
user_id: "trader001".to_string(),
|
|
roles: vec!["trader".to_string(), "risk_manager".to_string()],
|
|
permissions: vec![
|
|
Permission::SubmitOrders,
|
|
Permission::ViewPositions,
|
|
Permission::ModifyRiskLimits,
|
|
],
|
|
expires_at: chrono::Utc::now() + chrono::Duration::hours(8),
|
|
};
|
|
|
|
let jwt_token = generate_jwt_token(&token_payload, &jwt_secret)?;
|
|
println!("JWT token: {}", jwt_token);
|
|
|
|
// Validate JWT token
|
|
let validation_result = validate_jwt_token(&jwt_token, &jwt_secret)?;
|
|
if validation_result.is_valid {
|
|
println!("User authenticated: {}", validation_result.payload.user_id);
|
|
} else {
|
|
eprintln!("Authentication failed: {}", validation_result.error);
|
|
}
|
|
```
|
|
|
|
### Role-Based Access Control
|
|
|
|
```rust
|
|
use tli::auth::*;
|
|
|
|
// Check permissions
|
|
let user_context = UserContext {
|
|
user_id: "trader001".to_string(),
|
|
roles: vec!["trader".to_string()],
|
|
permissions: vec![Permission::SubmitOrders, Permission::ViewPositions],
|
|
};
|
|
|
|
// Permission checks
|
|
if user_context.has_permission(Permission::SubmitOrders) {
|
|
// Allow order submission
|
|
submit_order(&order_request).await?;
|
|
} else {
|
|
return Err(AuthError::InsufficientPermissions);
|
|
}
|
|
|
|
// Role-based resource access
|
|
if user_context.has_role("risk_manager") {
|
|
let risk_metrics = get_sensitive_risk_metrics().await?;
|
|
// Provide access to risk management functions
|
|
}
|
|
```
|
|
|
|
### TLS/mTLS Configuration
|
|
|
|
```rust
|
|
use tli::security::*;
|
|
|
|
// Configure TLS server
|
|
let tls_config = TlsConfig {
|
|
cert_path: "/opt/foxhunt/certs/production/foxhunt-cert.pem".to_string(),
|
|
key_path: "/opt/foxhunt/certs/production/foxhunt-key.pem".to_string(),
|
|
ca_path: Some("/opt/foxhunt/certs/production/ca-cert.pem".to_string()),
|
|
require_client_cert: true, // mTLS
|
|
verify_client_cert: true,
|
|
};
|
|
|
|
let tls_acceptor = create_tls_acceptor(&tls_config)?;
|
|
|
|
// TLS client configuration
|
|
let client_config = TlsClientConfig {
|
|
ca_path: "/opt/foxhunt/certs/production/ca-cert.pem".to_string(),
|
|
client_cert_path: Some("/opt/foxhunt/certs/client/client-cert.pem".to_string()),
|
|
client_key_path: Some("/opt/foxhunt/certs/client/client-key.pem".to_string()),
|
|
verify_server_cert: true,
|
|
};
|
|
|
|
let tls_connector = create_tls_connector(&client_config)?;
|
|
```
|
|
|
|

|
|
|
|
## Error Handling Patterns
|
|
|
|
All APIs use consistent error handling patterns with the `Result<T, E>` type:
|
|
|
|
```rust
|
|
// Core error types
|
|
use core::{CoreError, CoreResult};
|
|
use ml::{MLError, MLResult};
|
|
use risk::{RiskError, RiskResult};
|
|
use data::{DataError, DataResult};
|
|
|
|
// Error handling example
|
|
let result: CoreResult<Price> = Price::from_str("invalid_price");
|
|
match result {
|
|
Ok(price) => println!("Price: {}", price),
|
|
Err(CoreError::ParseError { input, reason }) => {
|
|
eprintln!("Failed to parse price '{}': {}", input, reason);
|
|
}
|
|
Err(e) => eprintln!("Unexpected error: {}", e),
|
|
}
|
|
|
|
// Using the ? operator for error propagation
|
|
fn trading_operation() -> CoreResult<()> {
|
|
let price = Price::from_str("100.50")?;
|
|
let quantity = Quantity::from_str("1000")?;
|
|
let order = create_order(price, quantity)?;
|
|
submit_order(order)?;
|
|
Ok(())
|
|
}
|
|
```
|
|
|
|
## Performance Considerations
|
|
|
|
### Latency Optimization
|
|
|
|
```rust
|
|
// Measure critical path latency
|
|
let measurement = HftLatencyTracker::start_measurement();
|
|
|
|
// Critical trading operation
|
|
let order_result = submit_order_fast_path(&order).await?;
|
|
|
|
let latency_ns = measurement.end();
|
|
if latency_ns > MAX_CRITICAL_LATENCY_NS {
|
|
tracing::warn!("Latency exceeded target: {}ns", latency_ns);
|
|
}
|
|
|
|
record_latency_metric("order_submission", latency_ns);
|
|
```
|
|
|
|
### Memory Management
|
|
|
|
```rust
|
|
// Use stack allocation for hot paths
|
|
let mut price_buffer: [f64; 1024] = [0.0; 1024];
|
|
process_prices_simd(&mut price_buffer)?;
|
|
|
|
// Minimize allocations in critical sections
|
|
let order_pool = ObjectPool::<TradingOrder>::new(1000);
|
|
let order = order_pool.get();
|
|
// ... use order ...
|
|
order_pool.return_object(order);
|
|
```
|
|
|
|
### Batch Processing
|
|
|
|
```rust
|
|
// Batch operations for efficiency
|
|
let orders = vec![order1, order2, order3];
|
|
let results = submit_orders_batch(&orders).await?;
|
|
|
|
// Process results in batch
|
|
for (order, result) in orders.iter().zip(results.iter()) {
|
|
handle_order_result(order, result)?;
|
|
}
|
|
```
|
|
|

|
#### Lock-Free Structures
|
|
|
|
```rust
|
|
use core::prelude::*;
|
|
|
|
// High-performance concurrent structures
|
|
let ring_buffer = LockFreeRingBuffer::<HftMessage>::new(8192);
|
|
let spsc_queue = SPSCQueue::<TradingOrder>::new(1024);
|
|
let mpsc_queue = MPSCQueue::<MarketEvent>::new(4096);
|
|
|
|
// Atomic operations for metrics
|
|
let counter = AtomicCounter::new();
|
|
counter.increment();
|
|
let metrics = AtomicMetrics::new();
|
|
metrics.record_latency(latency_ns);
|
|
```
|
|
|
|
#### CPU Affinity and Real-Time Scheduling
|
|
|
|
```rust
|
|
use core::prelude::*;
|
|
|
|
#[cfg(target_os = "linux")]
|
|
{
|
|
// Initialize HFT CPU optimizations
|
|
initialize_hft_cpu_optimizations()?;
|
|
|
|
// Manual CPU affinity management
|
|
let affinity_manager = CpuAffinityManager::new();
|
|
let assignment = HftCoreAssignment {
|
|
trading_cores: vec![0, 1, 2, 3],
|
|
ml_cores: vec![4, 5, 6, 7],
|
|
io_cores: vec![8, 9],
|
|
};
|
|
affinity_manager.apply_assignment(&assignment)?;
|
|
}
|
|
```
|
|
|
|
#### Small Batch Optimization
|
|
|
|
```rust
|
|
use core::prelude::*;
|
|
|
|
// Optimized batch processing for HFT
|
|
let mut processor = SmallBatchProcessor::new();
|
|
let orders = vec![
|
|
OrderRequest::new("EURUSD", Side::Buy, 1000.0)?,
|
|
OrderRequest::new("GBPUSD", Side::Sell, 500.0)?,
|
|
];
|
|
|
|
let result = processor.process_batch(&orders)?;
|
|
let metrics = processor.get_metrics();
|
|
println!("Batch latency: {}μs", metrics.avg_latency_us);
|
|
```

## Core Performance APIs
|
|
|
|
### Module: `core::prelude`
|
|
|
|
The core performance infrastructure providing sub-50μs latency operations.
|
|
|
|
#### Types
|
|
|
|
```rust
|
|
use core::prelude::*;
|
|
|
|
// High-precision financial types (unified across system)
|
|
let price = Price::from_str("100.50")?; // Safe decimal representation
|
|
let quantity = Quantity::from_str("1000")?; // Prevents overflow
|
|
let order_id = OrderId::new(); // Unique identifiers
|
|
let timestamp = Timestamp::now(); // Microsecond precision
|
|
```
|
|
|
|
#### Timing Operations (14ns Precision)
|
|
|
|
```rust
|
|
use core::prelude::*;
|
|
|
|
// Ultra-low latency timing infrastructure
|
|
let timestamp = HardwareTimestamp::now(); // RDTSC-based timing
|
|
let latency_tracker = HftLatencyTracker::new();
|
|
|
|
// Critical path measurement
|
|
let measurement = latency_tracker.start_measurement();

|
```rust
|
|
use core::timing::HftLatencyTracker;
|
|
|
|
let tracker = HftLatencyTracker::new();
|
|
|
|
// Track order submission latency
|
|
let measurement = tracker.start_measurement();
|
|
let result = submit_order(order).await?;
|
|
let latency = measurement.end();
|
|
|
|
if latency.as_nanos() > 50_000 { // 50μs threshold
|
|
log::warn!("High latency detected: {}ns", latency.as_nanos());
|
|
}
|
|
```
|
|
|
|
### Metrics Collection

|
|
```rust
|
|
use core::lockfree::AtomicMetrics;

|
|
|
let metrics = AtomicMetrics::new();
|
|
|
|
// Increment counters
|
|
metrics.increment_counter("orders_submitted");
|
|
metrics.record_latency("order_latency", latency);
|
|
|
|
// Get snapshot
|
|
let snapshot = metrics.get_snapshot();
|
|
```
|
|
|
|
## Error Handling
|
|
|
|
All APIs use consistent error handling patterns:
|
|
|
|
```rust
|
|
use core::error::CoreResult;
|
|
use risk::error::RiskResult;
|
|
use ml::error::MLResult;
|
|
|
|
// Standard error handling
|
|
match trading_ops.submit_order(order).await {
|
|
Ok(result) => {
|
|
// Handle success
|
|
},
|
|
Err(TradingError::RiskCheckFailed { reason }) => {
|
|
// Handle risk rejection
|
|
},
|
|
Err(TradingError::BrokerError { broker, error }) => {
|
|
// Handle broker communication error
|
|
},
|
|
}
|
|
```
|
|
|
|
## Performance Guarantees
|
|
|
|
### Latency Targets
|
|
|
|
- **Order submission**: < 50μs (50 microseconds)
|
|
- **Risk checks**: < 10μs (10 microseconds)
|
|
- **Market data processing**: < 5μs (5 microseconds)
|
|
- **Timing operations**: < 14ns (14 nanoseconds)
|
|
|
|
### Throughput Targets
|
|
|
|
- **Orders per second**: > 10,000
|
|
- **Market data messages**: > 100,000/sec
|
|
- **Risk calculations**: > 1,000/sec
|
|
|
|
### Memory Usage
|
|
|
|
- **Lock-free structures**: Zero allocation in hot paths
|
|
- **SIMD operations**: Cache-line aligned (64-byte)
|
|
- **Memory pools**: Pre-allocated for consistent performance
|
|
|
|
## Authentication & Security
|
|
|
|
All TLI API calls require proper authentication:
|
|
|
|
```rust
|
|
use tli::auth::AuthToken;
|
|
|
|
let token = AuthToken::from_env("TLI_AUTH_TOKEN")?;
|
|
let client = TliClient::with_auth("http://localhost:50051", token).await?;
|
|
```
|
|
|
