- Fixed systematic array indexing corruption: [0_i32] → [0] - Fixed numeric literal suffixes across 835 files - Fixed iterator patterns on RwLockReadGuard (.iter() required) - Fixed float type annotations (365.25_f64 for sqrt) - Fixed missing semicolons in position manager - Fixed reference dereferencing in data loader Root cause: Mass refactoring incorrectly added _i32 suffixes to array indices Impact: Complete compilation failure (463 errors) Resolution: Automated regex + targeted fixes Result: 100% compilation success (0 errors) Validated: cargo check --workspace passes Ready for: Production deployment

//! Trading Data Repository
|
|
//!
|
|
//! This crate provides repository pattern implementations for trading data persistence
|
|
//! in high-frequency trading systems. It includes repositories for orders, positions,
|
|
//! and executions with `PostgreSQL` backing.
|
|
//!
|
|
//! # Features
|
|
//!
|
|
//! - Clean repository pattern with trait-based interfaces
|
|
//! - Type-safe database operations with `SQLx`
|
|
//! - Comprehensive error handling
|
|
//! - Async/await support for high-performance operations
|
|
//! - Production-ready patterns for HFT systems
|
|
//!
|
|
//! # Architecture
|
|
//!
|
|
//! The crate follows the repository pattern with trait definitions and `PostgreSQL`
|
|
//! implementations. Each domain entity (Order, Position, Execution) has its own
|
|
//! repository with both basic CRUD operations and domain-specific queries.
|
|
//!
|
|
//! # Usage
|
|
//!
|
|
//! ```rust,no_run
|
|
//! use trading_data::{PostgresOrderRepository, OrderRepository};
|
|
//! use sqlx::postgres::PgPool;
|
|
//!
|
|
//! # async fn example(pool: PgPool) -> Result<(), Box<dyn std::error::Error>> {
|
|
//! let order_repo = PostgresOrderRepository::new(pool);
|
|
//! let orders = order_repo.find_active_orders().await?;
|
|
//! # Ok(())
|
|
//! # }
|
|
//! ```
