{# THIS File is not automatically generated:
the below applies to the result of this template
#}// This file is automatically generated based on the file `./generated.rs.tera` when `cargo gen-syntax` is run
// Do not edit manually
//! 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.
