Struct GetResponse 

pub struct GetResponse {
    pub found: bool,
    pub value: Vec<u8>,
    pub seq: u64,
}

Fields

found: bool

false ↔ key not found (or tombstoned)

value: Vec<u8>

only meaningful when found = true

seq: u64

Engine sequence this key was last written at; 0 when absent. A coordinator that reads a key it does not write needs this to build an AgentTxnRead.observed_seq — without it, optimistic transactions can only be driven from inside the storage process. NOT the same clock as the Percolator read_ts fields elsewhere in this file: that is a packed HLC, this is the engine’s MVCC sequence.

Trait Implementations

impl Clone for GetResponse

fn clone(&self) -> GetResponse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Message for GetResponse

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,
