Struct OperationRecord 

pub struct OperationRecord {
    pub id: OperationId,
    pub kind: String,
    pub last_step: u32,
    pub data: Vec<u8>,
    pub started_by: String,
}

A journal row read as one committed value.

Fields

id: OperationId

Its local identity.

kind: String

The kind’s stable name, defined by its sync implementation.

last_step: u32

Last completed step; zero precedes the first step.

data: Vec<u8>

The kind’s encoded state, including fixed identities and causal views.

started_by: String

The initiating app method or coven.

Implementations

impl OperationRecord

pub fn next_step(&self, data: Vec<u8>) -> Result<OperationUpdate, DbError>

The step past this row, recording data, guarded by this row’s step against a stale caller. An operation’s steps fitting u32 is an invariant.
