 This document describes LSP extensions used by rust-analyzer.
 It's a best effort document, when in doubt, consult the source (and send a PR with clarification ;-) ).
 We aim to upstream all non Rust-specific extensions to the protocol, but this is not a top priority.

+All capabilities are enabled via `experimental` field of `ClientCapabilities` or `ServerCapabilities`.
+Requests which we hope to upstream live under `experimental/` namespace.

 * Where exactly are `SnippetTextEdit`s allowed (only in code actions at the moment)?

+## `CodeAction` Groups

+**Issue:** https://github.com/microsoft/language-server-protocol/issues/994
+
+**Client Capability:** `{ "codeActionGroup": boolean }`
+
+If this capability is set, `CodeAction` returned from the server contain an additional field, `group`:
+
+```typescript
+interface CodeAction {
+    title: string;
+    group?: string;
+    ...
+}
+```
+
+All code-actions with the same `group` should be grouped under single (extendable) entry in lightbulb menu.
+The set of actions `[ { title: "foo" }, { group: "frobnicate", title: "bar" }, { group: "frobnicate", title: "baz" }]` should be rendered as

+  +-------------+
+  | foo         |
+  +-------------+-----+
+  | frobnicate >| bar |
+  +-------------+-----+
+                | baz |
+                +-----+
+```
+
+Alternatively, selecting `frobnicate` could present a user with an additional menu to choose between `bar` and `baz`.
+
+### Example
+
+```rust
+fn main() {
+    let x: Entry/*cursor here*/ = todo!();
+}
+```
+
+Invoking code action at this position will yield two code actions for importing `Entry` from either `collections::HashMap` or `collection::BTreeMap`, grouped under a single "import" group.
+
+### Unresolved Questions
+
+* Is a fixed two-level structure enough?
+* Should we devise a general way to encode custom interaction protocols for GUI refactorings?
