Expand description

Contains a trait for persisting application-level data in a K,V store that is unique for this particular connection

Provided Methods§

source

fn get<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>, NetworkError>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Gets a value from the backend

source

fn remove<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>, NetworkError>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Removes a value from the backend, returning the previous value

source

fn set<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, value: Vec<u8>, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>, NetworkError>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Stores a value in the backend, either creating or overwriting any pre-existing value

source

fn get_all<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<HashMap<String, Vec<u8>>, NetworkError>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait,

Obtains the K,V map for this application

source

fn remove_all<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<HashMap<String, Vec<u8>>, NetworkError>> + Send + 'async_trait>>
where Self: Sync + 'async_trait, 'life0: 'async_trait,

Obtains a list of K,V pairs such that needle is a subset of the K value
