Struct PartitionContext 

pub struct PartitionContext {
    pub incarnation: u64,
    pub owner_generation: u64,
    pub metadata_op: u64,
}

Captured before an operation is sent. Retries and delayed offset writes retain this value; discovering a newer incarnation or owner does not authorize old work.

A poll reply carries the context that served it in its body (PollMessagesResponseHeader::context).

Fields

incarnation: u64

Metadata creation revision of the partition. It changes when the numeric partition ID is reused, so offsets and retry results never cross incarnations.

owner_generation: u64

Installed consumer-group owner generation; zero for operations without a group.

metadata_op: u64

Applied metadata frontier, sent as the request’s minimum_metadata_op.

impl StructuralPartialEq for PartitionContext

impl WireDecode for PartitionContext

fn decode(buf: &[u8]) -> Result<(Self, usize), WireError>

Decode from buf, consuming exactly the bytes needed. Returns the decoded value and the number of bytes consumed.

fn encode(&self, buf: &mut BytesMut)

Write the encoded representation into buf.

fn to_bytes(&self) -> Bytes
