Variants

Normal

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

Fields of Normal

self_arg: Identimplicit_into_iter: boolis_option_or_result: bool

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

FnOnceCall

A call to FnOnce::call_once, desugared from my_closure(a, b, c)

Operator

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

Fields of Operator

self_arg: Ident

DerefCoercion

Fields of DerefCoercion

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
