Trait Implementations

impl StorageBackend for VmgsStorageBackend

fn persist<'life0, 'async_trait>( &'life0 mut self, data: Vec<u8>, ) -> Pin<Box<dyn Future<Output = Result<(), StorageBackendError>> + Send + 'async_trait>>

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

Write data to a non-volatile storage medium.

fn restore<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>, StorageBackendError>> + Send + 'async_trait>>

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

Read any previously written data. Returns None if no data exists.
