Expand description
In-memory implementations of RDF datasets.
This module provides building blocks
for defining implementations of Dataset
and MutableDataset
,
with fine-tuned trade-offs between memory footprint and performance.
It also provides two pre-defined trade-offs:
FastDataset
and LightDataset
,
provided in different flavours
(default, small
, sync
).
This module is the twin of the graph
module.
See its documentation for more details.
Modules
Flavours of Dataset implementations with a smaller memory-footprint.
Flavours of Dataset implementations which are safe to share across threads.
Structs
A DatasetWrapper
indexing quads by graph name, then by subject, then by predicate, then by object.
A generic implementation of Dataset
and MutableDataset
,
storing its terms in a TermIndexMap
,
and its triples in a HashSet
.
A DatasetWrapper
indexing quads by object, then by graph name, then by predicate, then by subject.
Traits
A dataset wrapper wraps a Dataset
and overrides some of its methods.
An indexed dataset wrapper wraps an IndexedDataset
and augments some of its methods,
through hooks of the forme before_x
and after_x
.
Type Definitions
Type alias for fallible quad iterators produced by a dataset.
Type alias for results iterators produced by a dataset.
Type alias for fallible hashsets of terms produced by a dataset.
Type alias for the terms returned by a dataset.
A heavily indexed dataset. Fast to query but slow to load, with a relatively high memory footprint.
A generic in-memory dataset.
A dataset with no triple index. Fast to load but slow to query, with a relatively low memory footprint.
