Struct rustc_middle::hir::map::blocks::FnLikeNode[−][src]

pub struct FnLikeNode<'a> {
    node: Node<'a>,
}
Expand description

An FnLikeNode is a Node that is like a fn, in that it has a decl and a body (as well as a NodeId, a span, etc).

More specifically, it is one of either:

  • A function item,
  • A closure expr (i.e., an ExprKind::Closure), or
  • The default implementation for a trait method.

To construct one, use the Code::from_node function.

Fields

node: Node<'a>
