Enum rustc_ast::visit::FnKind

pub enum FnKind<'a> {
    Fn(FnCtxt, Ident, &'a FnSig, &'a Visibility, &'a Generics, Option<&'a Block>),
    Closure(&'a ClosureBinder, &'a FnDecl, &'a Expr),
}

Variants

Fn(FnCtxt, Ident, &'a FnSig, &'a Visibility, &'a Generics, Option<&'a Block>)

E.g., fn foo(), fn foo(&self), or extern "Abi" fn foo().

Closure(&'a ClosureBinder, &'a FnDecl, &'a Expr)

E.g., |x, y| body.

Implementations

impl<'a> FnKind<'a>

pub fn header(&self) -> Option<&'a FnHeader>

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

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

pub fn ctxt(&self) -> Option<FnCtxt>

Trait Implementations

impl<'a> Clone for FnKind<'a>

fn clone(&self) -> FnKind<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for FnKind<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Copy for FnKind<'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.
