b_trees is both an executable binary that can be run, and a library that can be used in Rust programs.
Installing the main executable
Assuming you have Rust/Cargo installed, run this command in a terminal:
cargo install b_trees
It will make the main command available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall b_trees uninstalls.
Adding b_trees library as a dependency
Run this command in a terminal, in your project's directory:
cargo add b_trees
To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:
b_trees = "0.0.12"
The b_trees library will be automatically available globally.
Read the b_trees library documentation.
