What is @codemirror/lang-rust?

@codemirror/lang-rust is a language support package for the CodeMirror 6 code editor, specifically designed to provide syntax highlighting, code folding, and other language-specific features for the Rust programming language.

What are @codemirror/lang-rust's main functionalities?

Syntax Highlighting

This feature provides syntax highlighting for Rust code. The code sample demonstrates how to set up a CodeMirror editor with Rust syntax highlighting.

import { rust } from '@codemirror/lang-rust';
import { EditorState } from '@codemirror/state';
import { EditorView, basicSetup } from '@codemirror/basic-setup';

const state = EditorState.create({
  doc: 'fn main() { println!("Hello, world!"); }',
  extensions: [basicSetup, rust()]
});

const view = new EditorView({
  state,
  parent: document.body
});

Code Folding

This feature allows for code folding in Rust code. The code sample shows how to set up a CodeMirror editor with Rust syntax highlighting and code folding capabilities.

import { rust } from '@codemirror/lang-rust';
import { foldGutter } from '@codemirror/fold';
import { EditorState } from '@codemirror/state';
import { EditorView, basicSetup } from '@codemirror/basic-setup';

const state = EditorState.create({
  doc: 'fn main() { println!("Hello, world!"); }',
  extensions: [basicSetup, rust(), foldGutter()]
});

const view = new EditorView({
  state,
  parent: document.body
});

Auto-completion

This feature provides auto-completion for Rust code. The code sample demonstrates how to set up a CodeMirror editor with Rust syntax highlighting and auto-completion.

import { rust } from '@codemirror/lang-rust';
import { autocompletion } from '@codemirror/autocomplete';
import { EditorState } from '@codemirror/state';
import { EditorView, basicSetup } from '@codemirror/basic-setup';

const state = EditorState.create({
  doc: 'fn main() { println!("Hello, world!"); }',
  extensions: [basicSetup, rust(), autocompletion()]
});

const view = new EditorView({
  state,
  parent: document.body
});
