+//! Implementation of the LSP for rust-analyzer.
+//!
+//! This crate takes Rust-specific analysis results from ra_ide and translates
+//! into LSP types.
+//!
+//! It also is the root of all state. `world` module defines the bulk of the
+//! state, and `main_loop` module defines the rules for modifying it.
+//!
+//! The `cli` submodule implements some batch-processing analysis, primarily as
+//! a debugging aid.
