01_Faster_Compilation_Rust

• echo로 빠르게 넣기 rust-toolchain.toml & .cargo

멀티 쓰레드 숫자가 8이상은 되어야 효과가 있는듯 싶다.

• 여러가지 환경에서 test중..

• 글을 잘 읽어보니 크기와 최적화에 따라서 효과 편찬가 큰듯 싶다.

• Nitghtly에서 하는거라 여러 보안점을 추가한 후에 추후에 정식 버젼으로 들어올듯 싶다.

How to use it(Nightly 231109 기준)

https://doc.rust-lang.org/beta/cargo/reference/registry-authentication.html

https://blog.rust-lang.org/2023/11/09/parallel-rustc.html

The nightly compiler is now shipping with the parallel front-end enabled. However, by default it runs in single-threaded mode and won't reduce compile times.

Keen users can opt into multi-threaded mode with the -Z threads option. For example:

$ RUSTFLAGS="-Z threads=8" cargo build --release

Alternatively, to opt in from a config.toml file (for one or more projects), add these lines:

• 경로 맞는지는 테스트 해봐야함
• ~/.cargo/config.toml

[build]
rustflags = ["-Z", "threads=8"]

Available Parallelism : Cpu 갯수 체크하기

fn main() {
    println!(
        "You can use {:?} threads(available_parallelism) now.  ",
        std::thread::available_parallelism().unwrap()
    );
}
