Enum eventstore::prelude::ExpectedRevision

source · [−]

pub enum ExpectedRevision {
    Any,
    StreamExists,
    NoStream,
    Exact(u64),
}

Expand description

Constants used for expected version control. The use of expected version can be a bit tricky especially when discussing assurances given by the GetEventStore server.

The GetEventStore server will assure idempotency for all operations using any value in ExpectedRevision except ExpectedRevision::Any. When using ExpectedRevision::Any, the GetEventStore server will do its best to assure idempotency but will not guarantee idempotency.

Variants

`Any`

This write should not conflict with anything and should always succeed.

`StreamExists`

The stream should exist. If it or a metadata stream does not exist, treats that as a concurrency problem.

`NoStream`

The stream being written to should not yet exist. If it does exist, treats that as a concurrency problem.

`Exact(u64)`

States that the last event written to the stream should have an event number matching your expected value.
