Struct Handle 

pub struct Handle {
    pub memory: ManagedMemoryHandle,
    pub offset_start: Option<u64>,
    pub offset_end: Option<u64>,
    pub stream: StreamId,
    /* private fields */
}

Server handle containing the memory handle.

Fields

memory: ManagedMemoryHandle

Memory handle.

offset_start: Option<u64>

Memory offset in bytes.

offset_end: Option<u64>

Memory offset in bytes.

stream: StreamId

The stream where the data was created.

Implementations

impl Handle

pub fn from_memory(id: ManagedMemoryHandle, stream: StreamId, size: u64) -> Self

Creates a new handle of the given size.

pub fn new(stream: StreamId, size: u64) -> Self

Creates a new handle of the given size.

pub fn can_mut(&self) -> bool

Checks whether the handle can be mutated in-place without affecting other computation.

pub fn binding(self) -> Binding

Returns the Binding corresponding to the current handle.

pub fn offset_start(self, offset: u64) -> Self

Add to the current offset in bytes.

pub fn offset_end(self, offset: u64) -> Self

Add to the current offset in bytes.

pub fn copy_descriptor( self, shape: Shape, strides: Strides, elem_size: usize, ) -> CopyDescriptor

Convert the handle into a binding with shape and stride metadata.

pub fn size_in_used(&self) -> u64

Get the size of the handle, in bytes, accounting for offsets

pub fn size(&self) -> u64

Get the total size of the handle, in bytes.
