Enum FnKind

source
pub enum FnKind<'a> {
    Fn(&'a mut FnSig, &'a mut Generics, &'a mut Option<P<Block>>),
    Closure(&'a mut ClosureBinder, &'a mut P<FnDecl>, &'a mut P<Expr>),
}

Variants§

§

Fn(&'a mut FnSig, &'a mut Generics, &'a mut Option<P<Block>>)

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

§

Closure(&'a mut ClosureBinder, &'a mut P<FnDecl>, &'a mut P<Expr>)

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