Struct `Error`

struct Error(_)

Errors encountered by the timer implementation.

Currently, there are two different errors that can occur:

shutdown occurs when a timer operation is attempted, but the timer instance has been dropped. In this case, the operation will never be able to complete and the shutdown error is returned. This is a permanent error, i.e., once this error is observed, timer operations will never succeed in the future.
at_capacity occurs when a timer operation is attempted, but the timer instance is currently handling its maximum number of outstanding sleep instances. In this case, the operation is not able to be performed at the current moment, and at_capacity is returned. This is a transient error, i.e., at some point in the future, if the operation is attempted again, it might succeed. Callers that observe this error should attempt to shed load. One way to do this would be dropping the future that issued the timer operation.

Implementations

fn shutdown() -> Error: Creates an error representing a shutdown timer.
fn is_shutdown(self: &Self) -> bool: Returns true if the error was caused by the timer being shutdown.
fn at_capacity() -> Error: Creates an error representing a timer at capacity.
fn is_at_capacity(self: &Self) -> bool: Returns true if the error was caused by the timer being at capacity.
fn invalid() -> Error: Creates an error representing a misconfigured timer.
fn is_invalid(self: &Self) -> bool: Returns true if the error was caused by the timer being misconfigured.

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

fn into(self: Self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of [From]<T> for U chooses to do.
