Struct UVecUninitTxBuffer

pub struct UVecUninitTxBuffer { /* private fields */ }

Owned uninitialized buffer useful for tests and examples.

Implementations

impl UVecUninitTxBuffer

pub fn new(metadata: UFrameMetadata, payload_len: usize) -> Self

Creates an owned uninitialized transmit buffer.

pub fn with_alignment( metadata: UFrameMetadata, payload_len: usize, alignment: usize, ) -> Result<Self, UStatus>

Creates an owned uninitialized transmit buffer whose visible payload starts at alignment.

Errors

Returns an error if the requested alignment is invalid or allocation size overflows.

Trait Implementations

impl Clone for UVecUninitTxBuffer

fn clone(&self) -> UVecUninitTxBuffer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UVecUninitTxBuffer

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

Formats the value using the given formatter.

impl UUninitTxBuffer for UVecUninitTxBuffer

unsafe fn assume_payload_init(self) -> Self::Initialized

Safety

Caller upholds the documented loan/witness contract for this handle: exclusive, layout-valid storage (constructors) or complete initialization of every transported byte (witness discharges).

type Initialized = UVecTxBuffer

Initialized transmit loan type produced after payload initialization.

fn metadata(&self) -> &UFrameMetadata

Returns the immutable frame metadata associated with this transmit loan.

fn payload_len(&self) -> usize

Returns the visible application payload length.

fn payload_uninit_mut(&mut self) -> &mut [MaybeUninit<u8>]

Returns mutable uninitialized application payload storage.
