Struct sanakirja::Env

pub struct Env { /* fields omitted */ }

Environment, required to start any transactions. Thread-safe, but opening the same database several times in the same process is not cross-platform.

Methods

impl Env

fn file_size<P: AsRef<Path>>(path: P) -> Result<u64, Error>

File size of the database path, if it exists.

fn size(&self) -> u64

Length of the environment.

fn new<P: AsRef<Path>>(path: P, length: u64) -> Result<Env, Error>

Initialize an environment. length must be a strictly positive multiple of 4096. The same file can only be open in one process or thread at the same time, and this is enforced by a locked file.

fn txn_begin<'env>(&'env self) -> Result<Txn<'env>, Error>

Start a read-only transaction.

fn mut_txn_begin<'env>(&'env self) -> Result<MutTxn<'env, ()>, Error>

Start a mutable transaction. Mutable transactions that go out of scope are automatically aborted.

Trait Implementations

impl Send for Env

impl Sync for Env

impl Drop for Env

fn drop(&mut self)

A method called when the value goes out of scope.
