Trait SyntaxNodeExt

pub trait SyntaxNodeExt {
    // Required methods
    fn except_comments(&self) -> impl Iterator<Item = SyntaxToken> + '_;
    fn rule_exceptions(&self) -> HashSet<String>;
    fn is_rule_excepted(&self, id: &str) -> bool;
}

An extension trait for syntax nodes.

Required Methods

fn except_comments(&self) -> impl Iterator<Item = SyntaxToken> + '_

Gets an iterator over the @except comments for a syntax node.

fn rule_exceptions(&self) -> HashSet<String>

Gets the AST node’s rule exceptions set.

The set is the comma-delimited list of rule identifiers that follows a #@ except: comment.

fn is_rule_excepted(&self, id: &str) -> bool

Determines if a given rule id is excepted for the syntax node.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
