name: build-compile description: Build Rust code with proper error handling and optimization for development, testing, and production. Use when compiling the self-learning memory project or troubleshooting build errors.

Build and Compile

Build Rust code with proper error handling and optimization.

Build Commands

Build Profiles

Copy[profile.dev]
opt-level = 0
debug = true

[profile.release]
opt-level = 3
lto = "fat"
codegen-units = 1
strip = true

Common Errors

Type Errors

Copyerror[E0308]: mismatched types

Fix: Ensure return types match

Lifetime Errors

Copyerror[E0597]: value does not live long enough

Fix: Clone data or return owned type

Trait Bound Errors

Copyerror[E0277]: trait bound `X: Send` not satisfied

Fix: Use Send-safe types (Arc<Mutex>)

Async Errors

Copyerror: await only allowed in async functions

Fix: Make function async

Speed Up Builds

Copy# Incremental
export CARGO_INCREMENTAL=1

# Clean rebuild
cargo clean && cargo build --all

# Parallel jobs
cargo build -j 8

Optimization Tips

• LTO: lto = "fat" in release
• Codegen units: codegen-units = 1
• Profile: cargo build --timings
