Speed up Rust compilation by enabling parallel builds with all CPU cores and native CPU optimizations.
Enable parallel compilation and incremental builds to speed up Rust compilation times. Run the following command to build your project with multiple jobs and incremental caching:
RUSTFLAGS="-C target-cpu=native" cargo build --release -j $(nproc)
This sets the CPU target to native for optimizations, builds the release profile, and uses all available CPU cores for parallel compilation.
Optimizing compilation time involves using a command that tells your computer to use all its processing power at once to build your program, rather than doing it one step at a time. It also saves intermediate work so you don't have to start from scratch every time you make a small change. Think of it like hiring a whole team of workers instead of just one to finish a construction project faster.
