[−][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 |
Structs
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. |
Enums
Error | Main error type for this lmdb |
Functions
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 |
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. |
