Variants

Normal

Fields

self_arg: Option<Ident>
desugaring: Option<(CallDesugaringKind, Ty<'tcx>)>
is_option_or_result: bool

Whether the self type of the method call has an .as_ref() method. Used for better diagnostics.

A normal method call of the form receiver.foo(a, b, c)

FnCall

Fields

fn_trait_id: DefId
self_ty: Ty<'tcx>

A call to Fn(..)::call(..), desugared from my_closure(a, b, c)

Operator

Fields

self_arg: Option<Ident>
trait_id: DefId
self_ty: Ty<'tcx>

A call to an operator trait, desugared from operator syntax (e.g. a << b)

DerefCoercion

Fields

deref_target: Span

The Span of the Target associated type in the Deref impl we are using.

deref_target_ty: Ty<'tcx>

The type T::Deref we are dereferencing to

self_ty: Ty<'tcx>

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.
