Rust API
The Rust documentation is the single source of truth for the Substrate code base. However, if you aren't sure what you are looking for—for example, a specific crate, trait, or data structure—it can be tricky to navigate or to know the best place to start.
As discussed in Architecture and Rust libraries, Substrate libraries use a naming convention to indicate whether a library is part of the Substrate core client (sc_*), FRAME and the runtime (frame_* and pallet_*), or a Substrate primitive (sp_*).
If you don't have a specific crate in mind, use the following links as entry points to explore the core Rust libraries.
