Trait StateStore 

pub trait StateStore: Send + Sync {
    // Required methods
    fn get(
        &self,
        key: &str,
    ) -> impl Future<Output = Result<Option<Vec<u8>>>> + Send;
    fn set(
        &self,
        key: &str,
        value: &[u8],
        ttl_secs: Option<u64>,
    ) -> impl Future<Output = Result<Option<Vec<u8>>>> + Send;
    fn delete(&self, key: &str) -> impl Future<Output = Result<()>> + Send;
}

The StateStore trait defines the behavior storing and retrieving train state.

Required Methods

fn get(&self, key: &str) -> impl Future<Output = Result<Option<Vec<u8>>>> + Send

Retrieve a previously stored value from the state store.

fn set( &self, key: &str, value: &[u8], ttl_secs: Option<u64>, ) -> impl Future<Output = Result<Option<Vec<u8>>>> + Send

Store a value in the state store.

fn delete(&self, key: &str) -> impl Future<Output = Result<()>> + Send

Delete a value from the state store.

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.
