Struct BytesStorage 

pub struct BytesStorage { /* private fields */ }

The bytes storage maps IDs to reference-counted, initialized allocations. Removing an ID prevents new lookups; outstanding resources/guards keep the allocation alive until their last owner is dropped.

Implementations

impl BytesStorage

pub fn with_relocation_barrier( self, barrier: impl Fn() + Send + Sync + 'static, ) -> Self

Wait for the backend’s execution queue before resolving relocation copies.

pub fn try_get( &self, handle: &StorageHandle, ) -> Result<BytesResource, BytesAccessError>

Validate an ID and its byte range before exposing a resource.

Trait Implementations

impl ComputeStorage for BytesStorage

type Resource = BytesResource

The resource associated type determines the way data is implemented and how it can be accessed by kernels.

fn alignment(&self) -> usize

The alignment memory is allocated with in this storage.

fn get(&mut self, handle: &StorageHandle) -> Self::Resource

Returns the underlying resource for a specified storage handle

fn get_pinned( &mut self, handle: &StorageHandle, binding: ManagedMemoryBinding, ) -> Self::Resource

Resolve a resource while retaining its address lease in adaptive mode.

fn supports_relocation(&self) -> bool

Whether this storage implements real relocation copies and completion waits.

fn relocation_barrier(&mut self) -> Result<(), IoError>

Wait for all users of storage addresses, including work on other streams.

fn relocation_copy( &mut self, source: &StorageHandle, target: &StorageHandle, ) -> Result<(), IoError>

Enqueue a device-local copy between disjoint, equally sized reservations.

fn relocation_complete(&mut self) -> Result<(), IoError>

Wait for copies even when an earlier enqueue failed. Failure is not completion.

fn alloc(&mut self, size: u64) -> Result<StorageHandle, IoError>

Allocates size units of memory and returns a handle to it

fn dealloc(&mut self, id: StorageId)

Deallocates the memory pointed by the given storage id.

fn flush(&mut self)

Flush deallocations when required.

fn available_memory(&self) -> Option<u64>

Driver-reported free device memory in bytes; None when it is unknown.

fn relocation_copy_batch<'a>( &mut self, copies: impl IntoIterator<Item = (&'a StorageHandle, &'a StorageHandle)>, ) -> Result<(), IoError>

where Self: Sized,

Enqueue a group of relocation copies, with completion checked separately.

impl Debug for BytesStorage

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

Formats the value using the given formatter.

impl Default for BytesStorage

fn default() -> Self

Returns the “default value” for a type.
