Trait Implementations

impl Blob for UnreliableBlob

fn get<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<SegmentedBytes>, ExternalError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns a reference to the value corresponding to the key.

fn list_keys_and_metadata<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key_prefix: &'life1 str, f: &'life2 mut (dyn FnMut(BlobMetadata<'_>) + Send + Sync), ) -> Pin<Box<dyn Future<Output = Result<(), ExternalError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

List all of the keys in the map with metadata about the entry.

fn set<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, value: Bytes, ) -> Pin<Box<dyn Future<Output = Result<(), ExternalError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Inserts a key-value pair into the map.

fn delete<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<usize>, ExternalError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Remove a key from the map.

fn restore<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), ExternalError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Restores a previously-deleted key to the map, if possible.
