Enum RustTaskCallbackCode

#[repr(i8)]
pub enum RustTaskCallbackCode {
    Success = 0,
    Cancelled = 1,
}

Passed to a RustTaskCallback function when the executor invokes them.

Every RustTaskCallback will be invoked eventually, this code is used to distinguish the times when it’s invoked successfully vs times when the callback is being called because the foreign executor has been cancelled / shutdown

Variants

Success = 0

Successful task callback invocation

Cancelled = 1

The ForeignExecutor has been cancelled.

This signals that any progress using the executor should be halted. In particular, Futures should not continue to progress.

Trait Implementations

impl Debug for RustTaskCallbackCode

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

Formats the value using the given formatter.

impl PartialEq for RustTaskCallbackCode

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

Tests for self and other values to be equal, and is used by ==.

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

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