Method metadata

alpm-package/src/package.rs:836–858

Reads all metadata from an [alpm-package] file. This method reads all the metadata entries in the package file and returns a [`Metadata`] struct containing the processed data. # Errors Returns an error if - reading the metadata entries fails, - parsing a metadata entry fails, - or if any of the required metadata files are not found in the package.
