Struct AckNackSubmessage 

pub struct AckNackSubmessage {
    pub reader_id: EntityId,
    pub writer_id: EntityId,
    pub reader_sn_state: SequenceNumberSet,
    pub count: i32,
    pub final_flag: bool,
}

ACKNACK-Submessage.

final_flag entspricht dem F-Bit im Submessage-Header (Spec §8.3.7.1.1). final=false verlangt vom Writer eine zeitnahe HEARTBEAT-Response.

Fields

reader_id: EntityId

Reader-EntityId (Quelle).

writer_id: EntityId

Writer-EntityId (Ziel).

reader_sn_state: SequenceNumberSet

Bitset der noch nicht empfangenen Sequence-Numbers.

count: i32

Count_t (zur Korrelation mit HEARTBEAT.count).

final_flag: bool

F-Flag: false = Writer soll zeitnah mit HEARTBEAT antworten.

Implementations

impl AckNackSubmessage

pub fn write_body(&self, little_endian: bool) -> (Vec<u8>, u8)

Encoded den Body. Liefert (bytes, flags).

pub fn read_body( body: &[u8], little_endian: bool, final_flag: bool, ) -> Result<Self, WireError>

Decoded den Body. final_flag wird vom Caller aus dem Submessage-Header extrahiert.

Errors

UnexpectedEof.

Trait Implementations

impl Clone for AckNackSubmessage

fn clone(&self) -> AckNackSubmessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AckNackSubmessage

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

Formats the value using the given formatter.

impl PartialEq for AckNackSubmessage

fn eq(&self, other: &AckNackSubmessage) -> 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.
