Enum rustc_hir_analysis::astconv::ExplicitLateBound

pub enum ExplicitLateBound {
    Yes,
    No,
}

New-typed boolean indicating whether explicit late-bound lifetimes are present in a set of generic arguments.

For example if we have some method fn f<'a>(&'a self) implemented for some type T, although f is generic in the lifetime 'a, 'a is late-bound so should not be provided explicitly. Thus, if f is instantiated with some generic arguments providing 'a explicitly, we taint those arguments with ExplicitLateBound::Yes so that we can provide an appropriate diagnostic later.

Trait Implementations

impl Clone for ExplicitLateBound

fn clone(&self) -> ExplicitLateBound

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExplicitLateBound

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

Formats the value using the given formatter.

impl PartialEq<ExplicitLateBound> for ExplicitLateBound

fn eq(&self, other: &ExplicitLateBound) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
