This component is responsible for operations that must preserve source text details such as comments and whitespace.
It is an internal crate used by the future Rust LSP and by the CodeMirror package's bundled formatter WebAssembly.

Future LSP functionality should build on the same source-level tooling layer rather than on the runtime core.
## Web editor components
The Web playground editor uses CodeMirror 6 with a generated Lezer parser.
