Support for the language server protocol is built into Kate through the LSP plugin, which is included by default.
It is preconfigured to use rust-analyzer for Rust sources since Kate 21.12.
Earlier versions allow 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:
To change rust-analyzer config options, start from the following example and put it into Kate's "User Server Settings" tab (located under the LSP Client settings):
