aur_official_catalog_dup.rs

1//! Detect AUR-selected installs whose `pkgname` also appears as an official/sync row in a catalog.
2
3use std::collections::HashSet;
4
5use crate::state::types::{PackageItem, Source};
6
7/// What: Names of AUR-sourced install items that also have an official/sync row in `catalog`.
8///
9/// Inputs:
10/// - `install`: Packages queued for install.
11/// - `catalog`: Result rows to scan (typically `all_results` chained with `results`).
12///
13/// Output:
14/// - Sorted unique names for stable UI.
15///
16/// Details:
17/// - Uses exact `pkgname` equality; does not compare `pkgbase` or providers.
