This intention is pretty slow for `impl Interator`, because it has a
ton of default methods which need to be substituted.
The proper fix here is to not compute the actual edit until the user
triggers the action, but that's awkward to do in the LSP right now, so
let's just put a profiling code for now.
3015: vscode: yet another refactor commit r=matklad a=Veetaha
It compiles, it runs in dev extension host, It bundles, it runs when bundled and installed.
Removed 5 lines of code as you like less code, especially TypeScript code)

3016: Fix unneeded `.` in `docs/user/README.md` r=kjeremy a=fusillicode
I hope I got the typo right 😅
Thanks a lot of this wonderful project 🙇

2981: vscode: Add ability to call onEnter without overriding "type". r=matklad a=71
Before this PR, the only way to get enhanced typing (right now, only with `onEnter`) was to override VS Code's `type` command. This leads to issues with extensions like [VsCodeVim](https://github.com/VSCodeVim/Vim) that need to override `type` as well.
This PR adds an additional command, `onEnter`. This command can be used with the following keybinding, which allows the user to get smart `onEnter` behavior without overriding `type`.
```json
{
"key": "enter",
"command": "rust-analyzer.onEnter",
"when": "editorTextFocus && editorLangId == rust"
}
```

2911: Implement collecting errors while tokenizing r=matklad a=Veetaha
Now we are collecting errors from `rustc_lexer` and returning them in `ParsedToken { token, error }` and `ParsedTokens { tokens, errors }` structures **([UPD]: this is now simplified, see updates bellow)**.
The main changes are introduced in `ra_syntax/parsing/lexer.rs`. It now exposes the following functions and types:
```rust
pub fn tokenize(text: &str) -> ParsedTokens;
pub fn tokenize_append(text: &str, parsed_tokens_to_append_to: &mut ParsedTokens);
pub fn first_token(text: &str) -> Option<ParsedToken>; // allows any number of tokens in text
pub fn single_token(text: &str) -> Option<ParsedToken>; // allows only a single token in text
pub struct ParsedToken { pub token: Token, pub error: Option<SyntaxError> }
pub struct ParsedTokens { pub tokens: Vec<Token>, pub errors: Vec<SyntaxError> }
pub enum TokenizeError { /* Simple enum which reflects rustc_lexer tokenization errors */ }
```
In the first commit I implemented it with iterators, but then decided that since this crate is ad hoc for `rust-analyzer` and we clearly see the places of its usage it would be better to simplify it to vectors.
This is currently WIP, because I want to add tests for error messages generated by the lexer.
I'd like to listen to you thoughts how to define these tests in `ra_syntax/test-data` dir.
Related issues: #223
**[UPD]**
After the PR review the API was simplified:
```rust
pub fn tokenize(text: &str) -> (Vec<Token>, Vec<SyntaxError>);
// Both lex functions do not check for unescape errors
pub fn lex_single_syntax_kind(text: &str) -> Option<(SyntaxKind, Option<SyntaxError>)>;
pub fn lex_single_valid_syntax_kind(text: &str) -> Option<SyntaxKind>;
// This will be removed in the next PR in favour of simlifying `SyntaxError` to `(String, TextRange)`
pub enum TokenizeError { /* Simple enum which reflects rustc_lexer tokenization errors */ }
// this is private, but may be made public if such demand would exist in future (least privilege principle)
fn lex_first_token(text: &str) -> Option<(Token, Option<SyntaxError>)>;
```
