Struct KvGet 

pub struct KvGet {
    pub v: u32,
    pub namespace: String,
    pub key: Vec<u8>,
    pub if_none_match: Option<u64>,
    pub min_position: Option<MutationPosition>,
}

Request to read the value at key in namespace. With if_none_match set to a version, the read returns KvOutcome::NotModified instead of the value when the live version matches (a conditional GET), so an up-to-date cache skips the body transfer.

With min_position set, the read is barriered: the answering fold must have applied at least that MutationPosition before reading, so a takeover reader cannot observe a fold that predates its own lease acquisition. The server waits a short bound and answers KvError::Stale when the fold does not catch up, never an absent value. Only a deployment advertising the KV_FENCED_LEASES capability honors the barrier: a pre-fencing plane ignores the field, so a client must not send it unless the bit is advertised. Absent keeps today’s immediate local read, byte-identical.
