4//! This module contains auto-generated Rust AST. Like `SyntaxNode`s, AST nodes
5//! are generic over ownership: `X<'a>` things are `Copy` references, `XNode`
6//! are Arc-based. You can switch between the two variants using `.owned` and
7//! `.borrowed` functions. Most of the code works with borowed mode, and only
8//! this mode has all AST accessors.

6//! This module contains auto-generated Rust AST. Like `SyntaxNode`s, AST nodes
7//! are generic over ownership: `X<'a>` things are `Copy` references, `XNode`
8//! are Arc-based. You can switch between the two variants using `.owned` and
9//! `.borrowed` functions. Most of the code works with borowed mode, and only
10//! this mode has all AST accessors.
