1//! Interface of a Rust codegen backend
2//!
3//! This crate defines all the traits that have to be implemented by a codegen backend in order to
4//! use the backend-agnostic codegen code in `rustc_codegen_ssa`.
5//!
6//! The interface is designed around two backend-specific data structures, the codegen context and
7//! the builder. The codegen context is supposed to be read-only after its creation and during the
8//! actual codegen, while the builder stores the information about the function during codegen and
9//! is used to produce the instructions of the backend IR.
10//!
11//! The traits contain associated types that are backend-specific, such as the backend's value or
12//! basic blocks.
