Enum TransactionOperationKind 

pub enum TransactionOperationKind {
    Insert,
    Update,
    Delete,
    Put,
}

Variants

Insert

Create; refused with PRECONDITION_FAILED (present) when the record exists.

Update

Merge value into the existing record; refused when it does not exist.

Delete

Put

Create or replace: the record becomes exactly value. The canonical form of an unconditional or version-guarded collection write, which creates an absent record and replaces an existing one on every runtime (docs/reference/public-api.md, “Collection write semantics”). Guards travel as preconditions, as for the others.
