Struct PreparedTxLoanSpec

pub struct PreparedTxLoanSpec { /* private fields */ }

Prepared zero-copy transmit request passed from the adapter to a core.

Implementations

impl PreparedTxLoanSpec

pub fn from_validated<W, C>( spec: UTxLoanSpec, codec: &C, ) -> Result<Self, UStatus>

where W: UWire, C: UWireMetadataCodecFor<W>,

Encodes validated metadata for a selected wire.

Errors

Returns an error if selected-wire metadata encoding fails.

pub fn from_encoded_parts( metadata: UFrameMetadata, encoded_metadata: impl Into<Vec<u8>>, payload_len: usize, payload_alignment: usize, ) -> Result<Self, UStatus>

Creates a prepared loan spec from metadata bytes that are already encoded for the selected wire associated with metadata.

This is an advanced adapter/core boundary helper for owned-loopback bridges. Callers must pass encoded_metadata produced by the same selected wire that will decode metadata on receive; this constructor validates the decoded metadata and payload layout but cannot prove that the opaque metadata bytes were produced by a particular wire.

Errors

Returns an error if metadata, payload presence, or payload alignment is invalid for a zero-copy transmit loan.

pub fn metadata(&self) -> &UFrameMetadata

Returns the decoded frame metadata used to prepare this request.

pub fn encoded_metadata(&self) -> &[u8]

Returns selected-wire encoded metadata bytes.

pub fn payload_len(&self) -> usize

Returns the visible application payload length requested from the core.

pub fn payload_alignment(&self) -> usize

Returns the visible application payload alignment requested from the core.

pub fn payload_alignment_proof(&self) -> PayloadAlignment

Returns the validated visible application payload alignment proof.

pub fn has_payload(&self) -> bool

Returns whether the request carries a payload, including a present empty payload.

pub fn into_parts(self) -> (UFrameMetadata, Vec<u8>, usize, usize)

Consumes this request and returns its parts.

Trait Implementations

impl Clone for PreparedTxLoanSpec

fn clone(&self) -> PreparedTxLoanSpec

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PreparedTxLoanSpec

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

Formats the value using the given formatter.

impl PartialEq for PreparedTxLoanSpec

fn eq(&self, other: &PreparedTxLoanSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
