Install

Install from Settings view by searching for ide-rust, or with the command line:

$ ppm install ide-rust

Development

After cloning install the package: pulsar -p install Link to development mode: pulsar -p link -d Open Pulsar in Dev Mode

Prerequisites

rust-analyzer must be installed manually, if possible on the PATH (otherwise configure this in the package settings). See https://rust-analyzer.github.io/manual.html#rust-analyzer-language-server-binary.

NOTE: On Windows, you can install it using choco: choco install rust-analyzer

No other packages or manual setup is required as these will be handled with user prompts after install. However, you may wish to install rustup with your OS package manager instead of following prompts to install via rustup.rs.

Configure rust-analyzer

rust-analyzer settings can be stored in a JSON file in the project directory.

It first looks for rust-analyzer.json. If the file does not exists, it then checks .config/rust-analyzer.json.

Refer to the rust-analyzer User Manual for the supported config options.

Examples

enable proc-macro support (from the User Manual)

{
    "cargo": {
        "loadOutDirsFromCheck": true,
    },
    "procMacro": {
        "enable": true,
    }
}

configure rust-fmt

{
    "rustfmt": {
        "extraArgs": ["+nightly"]
    }
}
