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