Crate rpmrepo_metadata

Expand description

A library for reading, writing, and managing RPM repository metadata.

RPM repository metadata consists of several XML files (primary.xml, filelists.xml, other.xml, repomd.xml, updateinfo.xml, comps.xml) that together describe the packages available in a repository. This crate provides both high-level APIs (Repository, RepositoryReader, RepositoryWriter) and lower-level streaming readers/writers for each metadata type.

With the read_rpm feature enabled, RPM packages can be read directly from disk via Package::from_file.

Structs§

Changelog: A changelog entry from an RPM package.
CompsCategory: A category from comps.xml, organizing groups into higher-level groupings.
CompsData: Parsed comps.xml data containing all group, category, environment, and langpack entries.
CompsEnvironment: An environment from comps.xml, defining a complete installation profile.
CompsEnvironmentOption: An optional group within a comps environment, with a default selection state.
CompsGroup: A package group from comps.xml, grouping related packages for installation.
CompsLangpack: A langpack mapping from comps.xml, associating packages with language pack patterns.
CompsPackageReq: A package requirement within a comps group.
CompsXml: Marker type for comps.xml read/write operations.
CompsXmlReader: Reader for comps.xml metadata (package groups, categories, and environments).
Evr: A full RPM “version” specifier has 3 different components - Epoch, Version, and Release.
FileIter: Iterator over file entries in a FileList, yielding FileRef values.
FileList: A collection of file entries with interned directory and basename components.

PrimaryXml: Marker type for primary.xml read/write operations.
RepomdData: Contents of a repomd.xml file: revision, metadata file records, and repository tags.
RepomdRecord: A single metadata file entry within repomd.xml (e.g. primary, filelists, other).
RepomdXml: Marker type for repomd.xml read/write operations.
Repository: A high level API for working with RPM repositories.
RepositoryOptions: Options for writing RPM repository metadata.
RepositoryReader: Helper for reading metadata from an RPM repository manually.
RepositoryWriter: Helper for writing RPM repository metadata manually.
Requirement: An RPM dependency entry (used for Provides, Requires, Conflicts, Obsoletes, etc.).
