Trait KeyedState 

pub trait KeyedState: Send + Sync {
    // Required methods
    fn key(&self) -> &[u8] ;
    fn clear(&self) -> impl Future<Output = Result<()>> + Send;
}

Keyed state trait.

Required Methods

fn key(&self) -> &[u8]

Get the state key.

fn clear(&self) -> impl Future<Output = Result<()>> + Send

Clear the state.

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.
