Expand description

A trait that all Ligature implementations implement.

Required methods

Returns all Datasets in a Ligature instance.

Check if a given Dataset exists.

Returns all Datasets in a Ligature instance that start with the given prefix.

Returns all Datasets in a Ligature instance that are in a given range (inclusive, exclusive].

Creates a dataset with the given name. TODO should probably return its own error type { InvalidDataset, DatasetExists, CouldNotCreateDataset }

Deletes a dataset with the given name. TODO should probably return its own error type { InvalidDataset, CouldNotDeleteDataset }

Initializes a QueryTx TODO should probably return its own error type CouldNotInitializeQueryTx

Initializes a WriteTx TODO should probably return its own error type CouldNotInitializeWriteTx
