Enum txn_types::Mutation[][src]

pub enum Mutation {
    Put((Key, Value)),
    Delete(Key),
    Lock(Key),
    Insert((Key, Value)),
    CheckNotExists(Key),
}

A row mutation.

Variants

Put((Key, Value))

Put Value into Key, overwriting any existing value.

Delete(Key)

Delete Key.

Lock(Key)

Set a lock on Key.

Insert((Key, Value))

Put Value into Key if Key does not yet exist.

Returns kvrpcpb::KeyError::AlreadyExists if the key already exists.

CheckNotExists(Key)

Check key must be not exist.

Returns kvrpcpb::KeyError::AlreadyExists if the key already exists.
