Enum TimerControlFailure 

pub enum TimerControlFailure {
    GenerationExhausted,
    DeadlineOverflow,
    DelayOutOfRange,
    DirectiveNotAllowed,
    ProviderBindingFailed,
}

Typed terminal failure in pure timer control.

Variants

GenerationExhausted

A new callback would exceed its generation counter’s maximum. Cancellation does not allocate a generation and cannot cause this failure.

DeadlineOverflow

Checked successor deadline arithmetic overflowed.

DelayOutOfRange

A requested relative delay cannot be encoded as u64 nanoseconds.

DirectiveNotAllowed

An internal erased proposal is inconsistent with its configured policy. Public callback result types cannot express a policy-invalid decision.

ProviderBindingFailed

A checked registry effect could not establish canonical provider ownership.

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for TimerControlFailure

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for TimerControlFailure

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.
