The trait for sources of Cargo packages and its built-in implementations.
A source is a provider that contains source files and metadata of packages. It provides a number of methods to fetch those package information, for example, querying metadata or downloading files for a package. These information then can be used as dependencies for other Cargo packages.
This module provides Source trait as an abstraction of different sources,
as well as SourceMap struct as a map of all available sources.
Several built-in implementations of Source trait are provided. Namely,
RegistrySource— A source that provides an index for people to query a crate’s metadata, and fetch files for a certain crate. crates.io falls into this category. So do local registry and sparse registry.DirectorySource— Files are downloaded ahead of time. Primarily designed for crates generated fromcargo vendor.GitSource— This gets crate information from a git repository.PathSource— This gets crate information from a local path on the filesystem.ReplacedSource— This manages the source replacement feature, redirecting operations on the original source to the replacement.
This module also contains SourceConfigMap, which is effectively the
representation of the [source.*] value in Cargo configuration.
