- 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

Agent 437 - Wave 7 Phase 3: Fix map_err wildcard patterns
|
|
|
|
## Task
|
|
Fix clippy::map_err_ignore errors by replacing .map_err(|_| ...) with .map_err(|e| ... format!("{}", e) ...)
|
|
|
|
## Execution
|
|
|
|
### Files Fixed
|
|
- common/src/types.rs: 7 errors fixed
|
|
|
|
### Changes Made
|
|
1. Line 1869: Fill quantity overflow error - capture and include error in message
|
|
2. Line 2471: Price parsing error - capture and include parse error
|
|
3. Line 2749: Decimal to Quantity conversion - capture and include conversion error
|
|
4. Line 2883: Quantity parsing error - capture and include parse error
|
|
5. Line 2925: Decimal to f64 conversion - capture and include conversion error
|
|
6. Line 3071: NUMERIC to Price conversion (SQLx) - capture and include TryFrom error
|
|
7. Line 3108: NUMERIC to Quantity conversion (SQLx) - capture and include TryFrom error
|
|
|
|
### Pattern Applied
|
|
All fixes followed the same pattern:
|
|
```rust
|
|
// Before:
|
|
.map_err(|_| SomeError { message: "fixed message".to_owned() })
|
|
|
|
// After:
|
|
.map_err(|e| SomeError { message: format!("fixed message: {}", e) })
|
|
```
|
|
|
|
## Verification
|
|
|
|
### Before
|
|
```bash
|
|
$ cargo clippy -p common --lib -- -D clippy::map_err_ignore 2>&1 | grep "^error:" | wc -l
|
|
7
|
|
```
|
|
|
|
### After
|
|
```bash
|
|
$ cargo clippy -p common --lib -- -D clippy::map_err_ignore 2>&1 | grep "^error:" | wc -l
|
|
0
|
|
```
|
|
|
|
## Results
|
|
|
|
✅ **SUCCESS**: All 7 map_err_ignore errors in common crate eliminated
|
|
✅ **VERIFIED**: cargo clippy -p common --lib passes with -D clippy::map_err_ignore
|
|
✅ **ERROR COUNT**: 7 → 0 (100% reduction in common crate)
|
|
|
|
## Notes
|
|
|
|
- The workspace has compilation errors in services/stress_tests preventing full workspace clippy scan
|
|
- Other crates (trading_engine, adaptive-strategy) have additional map_err_ignore violations
|
|
- The common crate is now fully compliant with clippy::map_err_ignore
|
|
- All error messages now preserve the original error context
