Set default LSP

[Mirko-von-Leipzig]

How do I configure the default LSP when helix launches without a target file?

99% of my workspaces are Rust. Currently my workflow is opening the Rust workspace with hx <workspace path>, usually hx .. This launches helix with the file picker, however no LSP is launched.

Rust-analyzer is only launched once I open a rust file. I'd like to have LSP functionality load immediately without having to pick a random rust file. Often I don't have a specific file in mind, but rather want to search symbols / diagnostics so picking a random file to start with is annoying.

I'd happily configure rust-analyzer as the fallback LSP; or a more fine-grained per working directory configuration. I have no language specific configurations; and helix config only contains key-mapping changes.

I assume I'm being an idiot; but search is failing me..
