Struct rustc_middle::hir::map::blocks::FnLikeNode

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

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>

Implementations

impl<'a> FnLikeNode<'a>

pub fn from_node(node: Node<'_>) -> Option<FnLikeNode<'_>>

Attempts to construct a FnLikeNode from presumed FnLike node input.

pub fn body(self) -> BodyId

pub fn decl(self) -> &'a FnDecl<'a>

pub fn span(self) -> Span

pub fn id(self) -> HirId

pub fn constness(self) -> Constness

pub fn asyncness(self) -> IsAsync

pub fn unsafety(self) -> Unsafety

pub fn kind(self) -> FnKind<'a>

fn handle<A, I, M, C>(self, item_fn: I, method: M, closure: C) -> A where
    I: FnOnce(ItemFnParts<'a>) -> A,
    M: FnOnce(HirId, Ident, &'a FnSig<'a>, Option<&'a Visibility<'a>>, BodyId, Span) -> A,
    C: FnOnce(ClosureParts<'a>) -> A,

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.
