pub fn copy_to_path<P: AsRef<Path>>(
    &self,
    path: P,
    option: CompactionOption
) -> Result<File>

pub unsafe fn copy_to_fd(
    &self,
    fd: mdb_filehandle_t,
    option: CompactionOption
) -> Result<()>

pub fn force_sync(&self) -> Result<()>

pub fn path(&self) -> &Path

Returns the canonicalized path where this env lives.

pub fn prepare_for_closing(self) -> EnvClosingEvent

Returns an EnvClosingEvent that can be used to wait for the closing event, multiple threads can wait on this event.

Make sure that you drop all the copies of Envs you have, env closing are triggered when all references are dropped, the last one will eventually close the environment.

Trait Implementations

impl Clone for Env

pub fn clone(&self) -> Env

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
