Implementations

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()
    .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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
