Trait for local storage implementations

Required Methods§

Source

fn set<'life0, 'life1, 'life2, 'async_trait, T>( &'life0 self, key: &'life1 str, value: &'life2 T, ) -> Pin<Box<dyn Future<Output = Result<(), StorageError>> + Send + 'async_trait>>
where T: 'async_trait + Serialize + Send + Sync, Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Store a value with the given key

Source

fn get<'life0, 'life1, 'async_trait, T>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<T>, StorageError>> + Send + 'async_trait>>
where T: 'async_trait + DeserializeOwned + Send + Sync, Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Retrieve a value by key

Source

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

Remove a value by key

Source

fn keys<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>, StorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Get all keys

Provided Methods§

Source

fn contains_key<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<bool, StorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Check if a key exists

Source

fn len<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<usize, StorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Get the number of stored items

Source

fn is_empty<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<bool, StorageError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Check if storage is empty

Source

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

Clear all stored data

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
