Struct WindowsFetchDataWaiterMetrics 

pub struct WindowsFetchDataWaiterMetrics { /* private fields */ }

Monotonic process-local counters for active fetch waiters and cancellation matching.

Implementations

impl WindowsFetchDataWaiterMetrics

pub const fn active_waiters(self) -> usize

Returns the number of hydration waiters currently registered for native cancellation.

pub const fn registered_waiters(self) -> u64

Returns the total number of waiters registered since this registry was created.

pub const fn cancellation_callbacks(self) -> u64

Returns the total number of cancellation callbacks applied to this registry.

pub const fn unmatched_cancellations(self) -> u64

Returns cancellation callbacks that matched no active waiter range.

pub const fn fully_matched_waiters(self) -> u64

Returns active waiters whose complete logical range was covered by a cancellation.

pub const fn partially_matched_waiters(self) -> u64

Returns active waiters retained because cancellation covered only part of their range.

pub const fn cancelled_waiters(self) -> u64

Returns waiter cancellations that won the core terminal race.

pub const fn already_cancelled_waiters(self) -> u64

Returns full-range cancellations repeated before the cancelled waiter unregistered.

pub const fn completion_races(self) -> u64

Returns full-range cancellations that lost to normal waiter completion.

pub const fn watchdog_timeouts(self) -> u64

Returns waiters cancelled by the local callback watchdog.

pub const fn progress_callbacks(self) -> u64

Returns provider progress samples accepted by the registry.

pub const fn progress_updates(self) -> u64

Returns progress samples that refreshed at least one active waiter deadline.

Trait Implementations

impl Clone for WindowsFetchDataWaiterMetrics

fn clone(&self) -> WindowsFetchDataWaiterMetrics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WindowsFetchDataWaiterMetrics

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

Formats the value using the given formatter.

impl Default for WindowsFetchDataWaiterMetrics

fn default() -> WindowsFetchDataWaiterMetrics

Returns the “default value” for a type.

impl PartialEq for WindowsFetchDataWaiterMetrics

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