Struct BackendStorageHandle 

pub struct BackendStorageHandle<T> { /* private fields */ }

Backend-owned buffer handle.

BackendStorageHandle::new creates an empty opaque handle. Use BackendStorageHandle::new_with_len when test or adapter code needs to model a non-empty backend allocation.

Examples

use tenferro_tensor::BackendStorageHandle;

let handle = BackendStorageHandle::<f64>::new(7);

Implementations

impl<T> BackendStorageHandle<T>

pub fn new(id: u64) -> Self

Create a new backend buffer handle.

Examples

use tenferro_tensor::BackendStorageHandle;

let handle = BackendStorageHandle::<f64>::new(1);
assert_eq!(tenferro_tensor::BackendStorage::len(&handle), 0);

pub fn new_with_len(id: u64, len: usize) -> Self

Create a new backend buffer handle with a logical element count.

Examples

use tenferro_tensor::{BackendStorage, BackendStorageHandle};

let handle = BackendStorageHandle::<f64>::new_with_len(1, 4);
assert_eq!(BackendStorage::len(&handle), 4);

Trait Implementations

impl<T: Send + Sync + 'static> BackendStorage<T> for BackendStorageHandle<T>

fn backend_family(&self) -> &'static str

Stable backend family identifier.

fn len(&self) -> usize

Number of logical elements in the backend allocation.

fn allocation_domain(&self) -> Option<AllocationDomainId>

Return the shared-allocation domain, when this buffer belongs to one.

fn allocation_id(&self) -> Option<AllocationId>

Return the stable physical allocation identity, when available.

fn as_any(&self) -> &dyn Any

Type-erased access for the backend crate that owns the concrete handle.

fn is_empty(&self) -> bool

Returns true when the backend allocation is empty.

fn map_read(&self) -> Result<HostReadGuard<'_, T>, HostAccessError>

Map the allocation for closure-scoped host reads.

fn map_write(&mut self) -> Result<HostWriteGuard<'_, T>, HostAccessError>

Map the allocation for closure-scoped host writes.

impl<T> Debug for BackendStorageHandle<T>

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