If `rust-analyzer` is not detected, Corrosion will prompt you for configuration of your Rust toolchain and language server with a link to the __Window > Preferences > Rust__ preference page; from here a button allows to download and configure `rust-analyzer`, but you can also reference another installation.
You'll need to close and reopen all .rs and Cargo files, or to restart the IDE, for this change to take effect.

+Support for the language server protocol is built into Kate through the LSP plugin, which is included by default.
+It is preconfigured to use Rls for rust sources, but allows you to use rust-analyzer through a simple settings change.
+In the LSP Client settings of Kate, copy the content of the third tab "default parameters" to the second tab "server configuration".
+Then in the configuration replace:
+[source,json]
+----
+ "rust": {
+ "command": ["rls"],
+ "rootIndicationFileNames": ["Cargo.lock", "Cargo.toml"],
+ "url": "https://github.com/rust-lang/rls",
+ "highlightingModeRegex": "^Rust$"

+[source,json]

+ "rust": {
+ "command": ["rust-analyzer"],
+ "rootIndicationFileNames": ["Cargo.lock", "Cargo.toml"],
+ "url": "https://github.com/rust-analyzer/rust-analyzer",
+ "highlightingModeRegex": "^Rust$"
+ },
+----
+Then click on apply, and restart the LSP server for your rust project.
