Enum rustc_ast_lowering::expr::FutureKind

enum FutureKind {
    Future,
    AsyncIterator,
}

Used by LoweringContext::make_lowered_await to customize the desugaring based on what kind of future we are awaiting.

Variants

Future

We are awaiting a normal future

AsyncIterator

We are awaiting something that’s known to be an AsyncIterator (i.e. we are in the header of a for await loop)

Trait Implementations

impl Clone for FutureKind

fn clone(&self) -> FutureKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FutureKind

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

Formats the value using the given formatter.

impl PartialEq for FutureKind

fn eq(&self, other: &FutureKind) -> 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.
