Crate rust_analyzer 

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.

Modules

cli

Various batch processing tasks, intended primarily for debugging.

command 🔒

Utilities for running a cargo command like cargo check or cargo test in a separate thread and parse its stdout/stderr.

config

Config used by the language server.

diagnostics 🔒

Book keeping for keeping diagnostics easily in sync with the client.

discover 🔒

Infrastructure for lazy project discovery. Currently only support rust-project.json discovery via a custom discover command.

flycheck 🔒

Flycheck provides the functionality needed to run cargo check to provide LSP diagnostics based on the output of the command.

global_state 🔒

The context or environment in which the language server functions. In our server implementation this is know as the WorldState.

handlers 🔒

line_index 🔒

Enhances ide::LineIndex with additional info required to convert offsets into lsp positions.

lsp

Custom LSP definitions and protocol conversions.

main_loop 🔒

The main loop of rust-analyzer responsible for dispatching LSP requests/replies and notifications back to the client.

mem_docs 🔒

In-memory document information.

op_queue 🔒

Bookkeeping to make sure only one long-running operation is being executed at a time.

reload 🔒

Project loading & configuration updates.

target_spec 🔒

See TargetSpec

task_pool 🔒

A thin wrapper around [stdx::thread::Pool] which threads a sender through spawned jobs. It is used in crate::global_state::GlobalState throughout the main loop.

test_runner 🔒

This module provides the functionality needed to run cargo test in a background thread and report the result of each test in a channel.

tracing

version 🔒

Code for representing rust-analyzer’s release version number.

Constants

MINIMUM_SUPPORTED_TOOLCHAIN_VERSION

Any toolchain less than this version will likely not work with rust-analyzer built from this revision.

Functions

from_json

main_loop

server_capabilities

version

Returns information about cargo’s version.
