Ctor(&'hir VariantData<'hir>)

Ctor refers to the constructor of an enum variant or struct. Only tuple or unit variants with synthesized constructors.

GenericParam(&'hir GenericParam<'hir>)

Crate(&'hir Mod<'hir>)

Infer(&'hir InferArg)


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:

    .and_then(|ctor_id| tcx.hir().find(tcx.hir().get_parent_node(ctor_id)))
    .and_then(|parent| parent.ident())

Get the fields for the tuple-constructor, if this node is a tuple constructor, otherwise None
