Struct TimerHandle 

pub struct TimerHandle { /* private fields */ }

Handle for cancelling a pending timer.

Ownership Semantics

TimerHandle is intentionally not Clone or Copy. This ensures:

• Unique ownership: Only one handle exists per scheduled timer.
• Single cancellation: Once cancel() consumes the handle, no double-cancel is possible.

Creation

Handles are only created by [BitWheelInner::insert]. The internal fields (gear, slot, key, when_offset) are not publicly constructible, guaranteeing that any handle passed to cancel() refers to a valid timer entry (assuming it hasn’t already fired).

Validity

A handle becomes invalid once its when_offset tick has passed (i.e., the timer has fired). Calling cancel() on an expired handle safely returns None.

Trait Implementations

impl Debug for TimerHandle

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

Formats the value using the given formatter.

impl Hash for TimerHandle

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TimerHandle

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