Implementations

impl Db

pub fn sync_dbs(location: impl AsRef<Path>) -> Result<Vec<Db>, Error>

Pass this "/var/lib/pacman". WIP: This is multithreaded, but threads are hard and this is probably naive.

pub fn local_db(location: impl AsRef<Path>) -> Result<Db, Error>

Pass this "/var/lib/pacman".

pub fn pkg(&self, pkgname: impl AsRef<str>) -> Option<&MetaPackage>

Get some package metadata from this Db. Helper function over this function’s source

pub fn provides(&self, provide: &Provide) -> bool

Determines if a Provide is provided by this db.

let db = Db::local_db("/var/lib/pacman").unwrap();
// This indicates any version
db.provides(&Provide::parse("java-environment").unwrap());
// Version 8 only
db.provides(&Provide::parse("java-environment=8").unwrap());
