Installation
To use rust-analyzer, you need a rust-analyzer binary, a text editor
that supports LSP, and the source code of the Rust standard library.
If you're using VS Code, the extension bundles a
copy of the rust-analyzer binary. For other editors, you'll need to
install the binary and configure your
editor.
Rust Standard Library
rust-analyzer will attempt to install the standard library source code
automatically. You can also install it manually with rustup.
rustup component add rust-src


Only the latest stable standard library source is officially supported
for use with rust-analyzer. If you are using an older toolchain or have
an override set, rust-analyzer may fail to understand the Rust source.
You will either need to update your toolchain or use an older version of
rust-analyzer that is compatible with your toolchain.
If you are using an override in your project, you can still force
rust-analyzer to use the stable toolchain via the environment variable
RUSTUP_TOOLCHAIN. For example, with VS Code or coc-rust-analyzer:
{ "rust-analyzer.server.extraEnv": { "RUSTUP_TOOLCHAIN": "stable" } }


Crates
There is a package named ra_ap_rust_analyzer available on
crates.io, for people
who want to use rust-analyzer programmatically.
For more details, see the publish
workflow.
