Some features of rust-analyzer requires support for custom commands on the client side. Specifically, hover & code lens need this. Stock LSP doesn't have a way for the server to know which client-side commands are available. For that reason, we historically were just sending the commands, not worrying whether the client supports then or not. That's not really great though, so in this PR we add infrastructure for the client to explicitly opt-into custom commands, via `extensions` field of the ClientCapabilities. To preserve backwards compatability, if the client doesn't set the field, we assume that it does support all custom commands. In the future, we'll start treating that case as if the client doesn't support commands. So, if you maintain a rust-analyzer client and implement `rust-analyzer/runSingle` and such, please also advertise this via a capability. |
