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

Trait Implementations

impl<'tcx> Clone for FnSelfUseKind<'tcx>

fn clone(&self) -> FnSelfUseKind<'tcx>

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
