Struct ResendRecord 

pub struct ResendRecord<const FRAME: usize = MAX_RESEND_FRAME_LEN> {
    pub frame: Vec<u8, FRAME>,
    pub source_route: Option<Vec<RouterHint, MAX_SOURCE_ROUTE_HOPS>>,
}

Sealed frame bytes and optional source route retained for retransmission.

When the coordinator sends an ACK-requested packet, it must keep a verbatim copy of the already-sealed frame for potential retransmission — not just the plaintext — because re-building and re-sealing would produce a different ciphertext and a different ACK tag, which the destination would not recognize.

ResendRecord stores up to FRAME bytes of the original sealed frame alongside any source route that may need to be re-injected into the frame header on retransmit. Records are created via ResendRecord::try_new and embedded inside PendingAck. The FRAME const generic must be at least as large as the largest unicast frame the application will send; oversized frames are rejected at queue time with crate::CapacityError.

Fields

frame: Vec<u8, FRAME>

Exact sealed frame bytes.

source_route: Option<Vec<RouterHint, MAX_SOURCE_ROUTE_HOPS>>

Optional source route retained for retransmission.

Implementations

impl<const FRAME: usize> ResendRecord<FRAME>

pub fn try_new( frame: &[u8], source_route: Option<&[RouterHint]>, ) -> Result<Self, CapacityError>

Copy frame bytes and an optional route into fixed-capacity storage.

Trait Implementations

impl<const FRAME: usize> Clone for ResendRecord<FRAME>

fn clone(&self) -> ResendRecord<FRAME>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const FRAME: usize> Debug for ResendRecord<FRAME>

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

Formats the value using the given formatter.

impl<const FRAME: usize> PartialEq for ResendRecord<FRAME>

fn eq(&self, other: &ResendRecord<FRAME>) -> 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.
