Struct TypedNodeList 

pub struct TypedNodeList<'a, G: TypedGrammar, T> { /* private fields */ }

Typed read-only view over a list node in the arena.

Used throughout generated AST APIs for child collections.

Implementations

impl<G: TypedGrammar, T> TypedNodeList<'_, G, T>

pub fn node_id(&self) -> G::NodeId

The arena node ID of this list, as the grammar’s typed node ID.

pub fn len(&self) -> usize

Number of children.

pub fn is_empty(&self) -> bool

Whether this list has no children.

impl<'a, G: TypedGrammar, T: GrammarNodeType<'a>> TypedNodeList<'a, G, T>

pub fn get(&self, index: usize) -> Option<T>

Get a child by index, or None if out of bounds or unresolvable.

pub fn iter(&self) -> impl Iterator<Item = T> + 'a

Iterate over children. Unresolvable IDs are silently skipped.
