Struct OffsetBuffer 

pub struct OffsetBuffer { /* private fields */ }

An OffsetBuffer is a new Buffer-like object that represents a sub-region (still contiguous) within an existing Buffer.

Implementations

impl OffsetBuffer

pub fn new(base: Buffer, offset: usize, size: usize) -> Result<Self>

Create a new offset view into an existing memory region.

Returns an error if the offset and length exceed the bounds of the base region.

pub fn from_inner_address( base: Buffer, address: usize, size: usize, ) -> Result<Self>

Creates an offset buffer from an absolute address within the base region.

pub fn offset(&self) -> usize

Get the offset relative to the base mapping.

pub fn base(&self) -> &Buffer

Access the underlying base region.

Trait Implementations

impl Clone for OffsetBuffer

fn clone(&self) -> OffsetBuffer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OffsetBuffer

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

Formats the value using the given formatter.

impl MemoryDescriptor for OffsetBuffer

fn addr(&self) -> usize

Base address of the memory region.

fn size(&self) -> usize

Size of the memory region in bytes.

fn storage_kind(&self) -> StorageKind

Type of storage backing this region.

fn as_any(&self) -> &dyn Any

Enable downcasting to concrete type.

fn nixl_descriptor(&self) -> Option<NixlDescriptor>

Get the NIXL descriptor for this memory region.
