Struct WindowsFetchDataWaiterRegistry 

pub struct WindowsFetchDataWaiterRegistry { /* private fields */ }

Shareable active-waiter registry for one or more CFAPI connection generations.

Correlation includes the session generation and every native operation key. A cancellation is forwarded to core only when it covers an entire waiter range. Partial overlap is recorded but retained because core waiter cancellation is atomic and CFAPI still requires bytes outside the cancellation range.

Implementations

impl WindowsFetchDataWaiterRegistry

pub fn new() -> Self

Creates an empty registry.

pub fn with_watchdog_config(config: WindowsFetchDataWatchdogConfig) -> Self

Creates a registry with a host-controlled watchdog configuration.

pub fn metrics(&self) -> WindowsFetchDataWaiterMetrics

Returns a point-in-time counter snapshot.

pub fn cancel( &self, snapshot: &WindowsCancelFetchDataSnapshot, ) -> Result<WindowsFetchDataCancellationOutcome>

Applies one owned CFAPI cancellation snapshot to correlated active waiters.

Errors

Returns an error when validation fails or an underlying backend, store, or platform operation fails.

pub fn report_progress( &self, snapshot: &WindowsCallbackInfoSnapshot, progress: WindowsFetchDataProgress, now: Instant, ) -> Result<usize>

Applies provider progress to all active waiters with the same native correlation and refreshes their local watchdog deadline.

Errors

Returns an error when validation fails or an underlying backend, store, or platform operation fails.

pub fn poll_watchdog(&self, now: Instant) -> WindowsFetchDataWatchdogOutcome

Cancels pending waiters whose watchdog deadline has elapsed. The host owns the polling cadence; this method never starts a timer or blocks a native callback thread.

Trait Implementations

impl Clone for WindowsFetchDataWaiterRegistry

fn clone(&self) -> WindowsFetchDataWaiterRegistry

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

Performs copy-assignment from source.

impl Debug for WindowsFetchDataWaiterRegistry

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

Formats the value using the given formatter.

impl Default for WindowsFetchDataWaiterRegistry

fn default() -> WindowsFetchDataWaiterRegistry

Returns the “default value” for a type.
