aur-fetch

aur-fetch是一个用于管理从AUR下载和比较软件包的crate。这个过程被分解为多个不同的步骤，以提供最大程度的控制，并确保用户确认阅读后再合并软件包。

注意：此crate仅处理获取软件包。它假定传递给它的软件包列表是pkgbases，因此不能与拆分软件包一起工作。要处理拆分软件包，必须使用AUR RPC从pkgname获取pkgbase。

use aur_fetch::Fetch;


let pkgs = vec!["discord", "spotify", "pacman-git"];

// Create our handle
let fetch = Fetch::new()?;

// Clone/Fetch the packages.
let fetched = fetch.download(&pkgs)?;

// Merge changes
fetch.merge(&fetched)?;

// Only diff packages that have not been reviewed
let to_diff = fetch.unseen(&pkgs)?;

// Print each diff
for (diff, pkg) in fetch.diff(&to_diff, true)?.iter().zip(pkgs.iter()) {
    println!("{}:", pkg);
    println!("{}", diff.trim());
}
