Adding `build_array` library as a dependency

Run this command in a terminal, in your project's directory:

cargo add build-array

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

build-array = "0.1.2"

The build_array library will be automatically available globally. Read the build_array library documentation.

    .unwrap();

assert_eq!(arr, [1, 2, 3]);
