Trait for types used as a file storage backend.

Required Associated Types

type Type

The type created when producing a reader or writer. Typically Self.

type OpenError

The error type.

type SyncError

The error type.

Required Methods

fn open_ro<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Self::Type, Self::OpenError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Opens a new Type instance in read-only mode.

fn open_rw<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Self::Type, Self::OpenError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Opens a new Type instance in read-write mode.

fn sync_all<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), Self::SyncError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Synchronizes data and metadata with the underlying buffer.

fn sync_data<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), Self::SyncError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Synchronizes data with the underlying buffer.
