Module cargo::core::source

Fundamental types and traits for sources of Cargo packages.

A source is a provider that contains source files and metadata of packages. It provides a number of methods to fetch those package informations, for example, querying metadata or downloading files for a package. These informations then can be used as dependencies for other Cargo packages.

Notably, this module contains

• Source trait as an abstraction of different sources
• SourceMap struct as a map of all available sources
• SourceId struct as an unique identifier for a certain source

For implementations of Source trait, see crate::sources.
