Implementations§

source§

impl<'hir> Node<'hir>

source

pub fn ident(&self) -> Option<Ident>

Get the identifier of this Node, if applicable.

§Edge cases

Calling .ident() on a Node::Ctor will return None because Ctors do not have identifiers themselves. Instead, call .ident() on the parent struct/variant, like so:

ctor
    .ctor_hir_id()
    .map(|ctor_id| tcx.parent_hir_node(ctor_id))
    .and_then(|parent| parent.ident())
