Racer Configuration Page

The extension supports several configuration parameters to configure racer.

Configuration Parameters

Racer Path

The "rust.racerPath" configuration parameter specifies a path to the racer's executable.

The possible values:

• "Some path" - the extension would try to use the path
• null - the extension would try to use the PATH variable of the environment

If the extension failed to start racer, autocompletion wouldn't be available.

Rust Source

The "rust.rustLangSrcPath" configuration parameter specifies a path to the src directory of Rust sources.

The possible values:

• "Some path" - the extension would try to use the path. If it failed the extension would try another ways to find Rust sources.
• null - the extension would try another ways to find Rust sources.

The extension tries finding Rust sources in different places:

• The "rust.rustLangSrcPath" configuration parameter
• The RUST_SRC_PATH variable of the environment
• Rust sources installed via Rustup

If the extension failed to find Rust sources, racer wouldn't provide autocompletion for the standard library.

Cargo Home

The "rust.cargoHomePath" configuration parameter specifies a path to the home directory of Cargo.

I have never used this configuration parameter, but some people need it.
