This crate requires a nightly (unstable, experimental) compiler version. To switch to it, you must have Rust installed via Rustup, and run:
rustup default nightly
Run rustup default stable to switch back.
libsock is both an executable binary that can be run, and a library that can be used in Rust programs.
Installing the command-line executable
Assuming you have Rust/Cargo installed, run this command in a terminal:
cargo install libsock
It will make the libsock command available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall libsock uninstalls.
Adding libsock library as a dependency
Run this command in a terminal, in your project's directory:
cargo add libsock
To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:
libsock = "1.0.2"
The libsock library will be automatically available globally.
Read the libsock library documentation.
