Module storage 

Reusable storage layer: traits, a doublets-backed implementation and advisory locking helpers.

See LinksStorage for the abstraction the transactions layer is written against, and DoubletsStorage for the file-mapped doublets implementation.

Re-exports

pub use lock::lock_file_path;

pub use lock::FileLock;

pub use lock::LockMode;

Modules

lock

Advisory file locking for multi-process access to a links database.

Structs

DoubletsStorage

A LinksStorage over any doublets store.

PersistentFileMapped

A FileMapped region that does not wipe pre-existing file contents when doublets grows it.

StorageRevision

Cheap fingerprint of a database file, used to answer “has anyone else written since I last looked?” without reparsing.

Traits

LinksStorage

A store of links addressed by T, expressed in terms of owned GenericLink<T> values so that both in-memory maps and memory-mapped doublets stores can implement it.

LinksStorageRef

Extension implemented by stores that keep links resident in memory and can therefore lend out references instead of copies.

Type Aliases

FileMappedUnitStore

The file-mapped doublets store used by DoubletsStorage::open.
