Implementations

impl<'hir> HirNode<'hir>

pub fn format_node(&self, unit: CompileUnit<'hir>) -> String

pub fn base(&self) -> Option<&HirBase<'hir>>

Get the base information for any HIR node

pub fn kind(&self) -> HirKind

Get the kind of this HIR node

pub fn is_kind(&self, kind: HirKind) -> bool

Check if this node is of a specific kind

pub fn field_id(&self) -> u16

pub fn children(&self) -> &[HirId]

Get children of this node

pub fn kind_id(&self) -> u16

pub fn hir_id(&self) -> HirId

pub fn start_byte(&self) -> usize

pub fn end_byte(&self) -> usize

pub fn child_count(&self) -> usize

pub fn inner_ts_node(&self) -> Node<'hir>

pub fn parent(&self) -> Option<HirId>

pub fn opt_child_by_field( &self, unit: CompileUnit<'hir>, field_id: u16, ) -> Option<HirNode<'hir>>

pub fn child_by_field( &self, unit: CompileUnit<'hir>, field_id: u16, ) -> HirNode<'hir>

pub fn expect_ident_child_by_field( &self, unit: CompileUnit<'hir>, field_id: u16, ) -> &'hir HirIdent<'hir>

pub fn opt_child_by_kind( &self, unit: CompileUnit<'hir>, kind_id: u16, ) -> Option<HirNode<'hir>>

pub fn child_by_kind( &self, unit: CompileUnit<'hir>, kind_id: u16, ) -> HirNode<'hir>

pub fn find_ident( &self, unit: CompileUnit<'hir>, ) -> Option<&'hir HirIdent<'hir>>

Recursively search for an identifier within this node.

Useful for finding the actual identifier in complex AST nodes like generic_type that wrap the identifier. For example, in impl<'tcx> Holder<'tcx>, the type field points to a generic_type node, which contains the type_identifier “Holder”.
