Trait NodeAccess 

pub trait NodeAccess {
    // Required methods
    fn node_info(&self, index: NodeIndex) -> Option<NodeInfo>;
    fn kind(&self, index: NodeIndex) -> Option<u16>;
    fn pos_end(&self, index: NodeIndex) -> Option<(u32, u32)>;

    fn exists(&self, index: NodeIndex) -> bool { ... }
}

Trait for unified access to AST nodes across different arena implementations. This allows consumers (binder, checker, emitter) to work with either different arena implementations without code changes.

Required Methods

fn node_info(&self, index: NodeIndex) -> Option<NodeInfo>

Get basic node information by index

fn kind(&self, index: NodeIndex) -> Option<u16>

Get the syntax kind of a node

fn pos_end(&self, index: NodeIndex) -> Option<(u32, u32)>

Get the source position range

fn get_identifier_text(&self, index: NodeIndex) -> Option<&str>

Get identifier text (if this is an identifier node)

fn get_literal_text(&self, index: NodeIndex) -> Option<&str>

Get literal value text (if this is a literal node)

fn get_children(&self, index: NodeIndex) -> Vec<NodeIndex>

Get children of a node (for traversal)

Provided Methods

fn exists(&self, index: NodeIndex) -> bool

Check if a node exists
