[−][src]Crate grin_store

Storage of core types using RocksDB.

Modules

leaf_set	The Grin leaf_set implementation. Compact (roaring) bitmap representing the set of leaf positions that exist and are not currently pruned in the MMR.
pmmr	Implementation of the persistent Backend for the prunable MMR tree.
prune_list	The Grin "Prune List" implementation.
types	Common storage-related types

Batch	Batch to write multiple Writeables to db in an atomic manner.
SerIterator	An iterator thad produces Readable instances back. Wraps the lower level DBIterator and deserializes the returned values.
Store	LMDB-backed store facilitating data access and serialization. All writes are done through a Batch abstraction providing atomicity.

Main error type for this lmdb

new_env	Create a new LMDB env under the provided directory. By default creates an environment named "lmdb". Be aware of transactional semantics in lmdb (transactions are per environment, not per database).
new_named_env	TODO - We probably need more flexibility here, 500GB probably too big for peers... Create a new LMDB env under the provided directory with the provided name.
option_to_not_found	unwraps the inner option by converting the none case to a not found error
read_bitmap	Read Bitmap from a file
save_via_temp_file	Creates temporary file with name created by adding `temp_suffix` to `path`. Applies writer function to it and renames temporary file into original specified by `path`.
to_key	Build a db key from a prefix and a byte vector identifier.
to_key_u64	Build a db key from a prefix and a byte vector identifier and numeric identifier
u64_to_key	Build a db key from a prefix and a numeric identifier.
