1//! Implementation of the LSP for rust-analyzer.
2//!
3//! This crate takes Rust-specific analysis results from ide and translates
4//! into LSP types.
5//!
6//! It also is the root of all state. `world` module defines the bulk of the
7//! state, and `main_loop` module defines the rules for modifying it.
8//!
9//! The `cli` submodule implements some batch-processing analysis, primarily as
10//! a debugging aid.
11
12/// Any toolchain less than this version will likely not work with rust-analyzer built from this revision.
