339Please consult your editor's documentation to learn how to configure LSP servers. 339In general `rust-analyzer` is configured via LSP messages, which means that it's up to the editor to decide on the exact format and location of configuration files.

341To verify which configuration is actually used by rust-analyzer, set `RA_LOG` environment variable to `rust_analyzer=info` and look for config-related messages. 341Some clients, such as <<vs-code,VS Code>> or <<coc-rust-analyzer,COC plugin in Vim>> provide `rust-analyzer` specific configuration UIs. Others may require you to know a bit more about the interaction with `rust-analyzer`.
342Logs should show both the JSON that rust-analyzer sees as well as the updated config.

344This is the list of config options rust-analyzer supports: 343For the later category, it might help to know that the initial configuration is specified as a value of the `intializationOptions` field of the https://microsoft.github.io/language-server-protocol/specifications/specification-current/#initialize[`InitializeParams` message, in the LSP protocol].
344The spec says that the field type is `any?`, but `rust-analyzer` is looking for a JSON object that is constructed using settings from the list below.
345Name of the setting, ignoring the `rust-analyzer.` prefix, is used as a path, and value of the setting becomes the JSON property value.

347For example, a very common configuration is to enable proc-macro support, can be achieved by sending this JSON:
