Struct LogPosition 

pub struct LogPosition {
    pub stream_id: u32,
    pub topic_id: u32,
    pub partition_id: u32,
    pub offset: u64,
}

The Iggy binding’s packing of the causal locator (cause_at, and the dead-letter source).

The locator rides the wire as one opaque byte string, the substrate- neutral slot every binding packs its own form into, so the envelope itself names no server. A consumer that cannot interpret the bytes ignores them and falls back to the portable cause / record id. The Iggy packing is the four-level address as fixed-width big-endian payload: stream_id, topic_id, partition_id (each u32) then offset (u64), 20 bytes. Another binding packs its own locator (a topic name or id, a partition, an offset) into the same opaque slot.

Fields

stream_id: u32

topic_id: u32

partition_id: u32

offset: u64

Implementations

impl LogPosition

pub const fn new( stream_id: u32, topic_id: u32, partition_id: u32, offset: u64, ) -> Self

A locator at (stream, topic, partition, offset).

pub fn to_bytes(self) -> [u8; 20]

The Iggy locator packed as 20 big-endian bytes (the opaque wire form).

pub fn from_bytes(payload: [u8; 20]) -> Self

Unpack the Iggy locator from its 20 big-endian bytes.
