Struct DeviceLayerWindow 

pub struct DeviceLayerWindow { /* private fields */ }

Deterministic controller for a bounded ordered device-layer window.

Implementations

impl DeviceLayerWindow

pub fn new( units: impl IntoIterator<Item = OffloadUnitId>, depth: usize, ) -> Result<Self, ResidencyWindowError>

Creates a controller for a non-empty, duplicate-free unit sequence.

pub const fn depth(&self) -> usize

Returns the maximum number of ordered units kept on the device.

pub fn units(&self) -> &[OffloadUnitId]

Returns units in execution order.

pub fn desired( &self, current: usize, ) -> Result<&[OffloadUnitId], ResidencyWindowError>

Returns the desired window beginning at current.

pub fn prepare<M: ResidencyWindowManager>( &self, manager: &M, current: usize, ) -> Result<Vec<(OffloadUnitId, PrefetchOutcome)>, M::Error>

Prepares and trims the default window beginning at current.

pub fn trim_to<M: ResidencyWindowManager>( &self, manager: &M, desired: &[OffloadUnitId], ) -> Result<(), M::Error>

Explicitly evicts every managed device copy outside desired.

pub fn clear<M: ResidencyWindowManager>( &self, manager: &M, ) -> Result<(), M::Error>

Clears protection and removes every managed device copy.
