Struct SqlTxnOutput 

pub struct SqlTxnOutput {
    pub applied: bool,
    pub txn_id: Option<TxnWireId>,
    pub lmid_advance: Option<LmidAdvance>,
}

The outcome of a one-shot SqlTxn (or a mutation rejection) — and the exact shape a session commit answers, from either master. applied: false is an absorbed replay (mid ≤ lmid, seq ≤ last_seq) or a zero-effect no-op: nothing committed, no txn identity.

Fields

applied: bool

txn_id: Option<TxnWireId>

The commit’s identity in the backend’s own currency (None when nothing committed).

lmid_advance: Option<LmidAdvance>

The client’s watermark after this call (None for a foreign write).

Implementations

impl SqlTxnOutput

pub fn tx_id(&self) -> Option<TxId>

The rindled-flavor identity (the cluster commit), for callers that know their master. None on an absorbed/no-op outcome — or on a replicator cursor.

pub fn cursor(&self) -> Option<&str>

The replicator-flavor identity (the minted change-log cursor w:<seq>).

Trait Implementations

impl Clone for SqlTxnOutput

fn clone(&self) -> SqlTxnOutput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqlTxnOutput

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

Formats the value using the given formatter.

impl PartialEq for SqlTxnOutput

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