Rust LSP Configuration

The details below describe how to install and configure the Rust language server found here.
NOTE: This installation process assumes Rust has been installed on the machine.

Installing the Language Server

To install the language server run the following command:
rustup component add rls-preview rust-analysis rust-src
With the software installed test the installation by running rls.exe --help at the command line prompt, which should result in the following output:
    --version or -V to print the version and commit info
    --help or -h for this message
    --cli starts the RLS in command line mode
    No input starts the RLS as a language server
If that output is not produced refer to the the Rust language server page for more details.


Edit the Rust document type and in the Language Server configuration panel apply the following configuration settings:
Program Type: Executable
     Program: rls.exe
NOTE: The executable directory option can be omitted provided the executable folder is found in the system PATH environment variable.

Using the Language Server

To test the configuration you will need to create a Rust project and a Zeus workspace as described below.
1: Create a new Rust project as follow:
cd c:\Rust\
cargo new hello_world --bin
More details about Rust projects can be found here.
2: Create a new Zeus workspace in the hello_world folder and optionally add the hello_world\src files to that workspace.
3: Open the new Zeus workspace, open the hello_world\src\ file and fire off the auto-complete:
lsp rust
