Helper methods for storing/retrieving typed data

Provided Methods§

Source

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

Put a serializable value

Source

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

Get and deserialize a value

Source

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

List all values with a given prefix

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.
