Implementations

source

impl EnvWrite

source

pub fn open(
 path: &Path,
 kind: DbKind,
 keystore: KeystoreSender
) -> DatabaseResult<Self>

Constructor

source

pub fn test(
 tmpdir: &TempDir,
 kind: DbKind,
 keystore: KeystoreSender
) -> DatabaseResult<Self>

Test constructor

source

pub fn kind(&self) -> &DbKind

Kind Accessor

source

pub fn keystore(&self) -> KeystoreSender

Accessor

source

pub async fn remove(self) -> DatabaseResult<()>

Remove the db and directory

Methods from Deref<Target = DbWrite>

source

pub async fn async_commit<E, R, F>(&'_ self, f: F) -> Result<R, E> where
 E: 'static + From<DatabaseError> + Send,
 F: 'static + FnOnce(&mut Transaction<'_>) -> Result<R, E> + Send,
 R: 'static + Send,

source

pub async fn async_commit_in_place<E, R, F>(&'_ self, f: F) -> Result<R, E> where
 E: From<DatabaseError>,
 F: FnOnce(&mut Transaction<'_>) -> Result<R, E>,
 R: Send,

If possible prefer async_commit as this is slower and can starve chained futures.

Methods from Deref<Target = DbRead>

source

pub fn conn(&self) -> Result<PConn, DatabaseError>

source

pub fn inner(&self) -> DbRead

👎 Deprecated:

remove this identity function

source

pub fn kind(&self) -> &DbKind

Accessor for the DbKind of the DbWrite

source

pub fn path(&self) -> &PathBuf

The environment’s path

source

pub async fn async_reader<E, R, F>(&'_ self, f: F) -> Result<R, E> where
 E: 'static + From<DatabaseError> + Send,
 F: 'static + FnOnce(Transaction<'_>) -> Result<R, E> + Send,
 R: 'static + Send,
