//! Implementation of the LSP for rust-analyzer.
|
|
//!
|
|
//! This crate takes Rust-specific analysis results from 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.
