[−][src]Enum eventstore::types::ExpectedVersion
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 ExpectedVersion
except ExpectedVersion::Any
. When using
ExpectedVersion::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(i64)
States that the last event written to the stream should have an event number matching your expected value.
