Struct StorageEngine 

pub struct StorageEngine { /* private fields */ }

Implementations

impl StorageEngine

pub fn open_file(path: impl AsRef<Path>) -> Result<Self, StorageError>

Open (creating if absent) a single-file, on-disk database.

pub fn open_memory() -> Result<Self, StorageError>

Open a purely in-memory database. Nothing is written to disk and all data is lost when the StorageEngine is dropped.

pub fn begin_write(&self) -> Result<WriteTransaction, StorageError>

pub fn begin_read(&self) -> Result<ReadTransaction, StorageError>

pub fn check_integrity(&mut self) -> Result<bool, StorageError>

Run redb’s physical checksum/allocation integrity check. A false result means damage was found and repaired; an unrecoverable database is returned as an error.

pub fn backup_to(&self, path: impl AsRef<Path>) -> Result<(), StorageError>

Write a transactionally consistent copy of every MarsDB table to a new database file. The destination is created exclusively so an existing file is never silently overwritten.
