Attribute Macro realia::cmd

#[cmd]

Checks whether an executable exists on the PATH.

If you use this attribute, your project should include a build.rs that triggers a rebuild when the PATH environment variable changes:

fn main() {
    println!("cargo:rerun-if-env-changed=PATH");
}

Example

#[realia::cmd("git")]
fn example() {
    println!("Git is installed and available");
}
