pub async fn create_dir(&self, txn_id: TxnId, name: Id) -> TCResult<Self>
Create a new sub-directory with the given name
at txn_id
.

&self,
txn_id: TxnId,
name: Id
) -> TCResult<File<FE, B>>
pub async fn create_file<B>( &self, txn_id: TxnId, name: Id ) -> TCResult<File<FE, B>>

sourcepub async fn get_dir(&self, txn_id: TxnId, name: &Id) -> TCResult<Self>
pub async fn get_dir(&self, txn_id: TxnId, name: &Id) -> TCResult<Self>
Get the sub-Dir
with the given name
at txn_id
, or return a “not found” error.
sourcepub async fn get_or_create_dir(&self, txn_id: TxnId, name: Id) -> TCResult<Self>
pub async fn get_or_create_dir(&self, txn_id: TxnId, name: Id) -> TCResult<Self>
Get the sub-Dir
with the given name
at txn_id
, or create a new one.
sourcepub async fn get_file<B>(
&self,
txn_id: TxnId,
name: &Id
) -> TCResult<File<FE, B>>
pub async fn get_file<B>( &self, txn_id: TxnId, name: &Id ) -> TCResult<File<FE, B>>
Get the File
with the given name
at txn_id
, or return a “not found” error.
sourcepub async fn is_empty(&self, txn_id: TxnId) -> TCResult<bool>
pub async fn is_empty(&self, txn_id: TxnId) -> TCResult<bool>
