Struct DynamicNodeTypes 

pub struct DynamicNodeTypes { /* private fields */ }

Compiled node type database for a language (dynamic/heap-allocated).

Use this for runtime construction or as reference implementation. For zero-init static data, use StaticNodeTypes.

Implementations

impl DynamicNodeTypes

pub fn from_raw( nodes: HashMap<NodeTypeId, NodeTypeInfo>, extras: Vec<NodeTypeId>, root: Option<NodeTypeId>, ) -> Self

pub fn build<F, G>( raw_nodes: &[RawNode], node_id_for_name: F, field_id_for_name: G, ) -> Self

where F: Fn(&str, bool) -> Option<NodeTypeId>, G: Fn(&str) -> Option<NodeFieldId>,

Build from raw nodes and ID resolution functions.

pub fn get(&self, node_type_id: NodeTypeId) -> Option<&NodeTypeInfo>

pub fn contains(&self, node_type_id: NodeTypeId) -> bool

pub fn field( &self, node_type_id: NodeTypeId, field_id: NodeFieldId, ) -> Option<&FieldInfo>

pub fn children(&self, node_type_id: NodeTypeId) -> Option<&ChildrenInfo>

pub fn extras(&self) -> &[NodeTypeId]

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn iter(&self) -> impl Iterator<Item = (NodeTypeId, &NodeTypeInfo)>

pub fn sorted_node_ids(&self) -> Vec<NodeTypeId>

Get sorted vec of all node IDs (for conversion to static).

pub fn sorted_extras(&self) -> Vec<NodeTypeId>

Get sorted vec of extra IDs (for conversion to static).
