Trait libmacchina::traits::PackageReadout

pub trait PackageReadout {
    // Required method
    fn new() -> Self;

    // Provided method
    fn count_pkgs(&self) -> Vec<(PackageManager, usize)> { ... }
}

This trait provides an interface to various functions used to count packages on the host system. Almost all modern operating systems use some kind of package manager.

Example

use libmacchina::traits::{PackageReadout, PackageManager};
use libmacchina::traits::ReadoutError;

pub struct MacOSPackageReadout;

impl PackageReadout for MacOSPackageReadout {
    fn new() -> Self {
        MacOSPackageReadout {}
    }

    fn count_pkgs(&self) -> Vec<(PackageManager, usize)> {
        // Check if homebrew 🍻 is installed and count installed packages...
        vec![(PackageManager::Homebrew, 120)]
    }
}
