Trait StoreDeletable 

pub trait StoreDeletable: StoreMut {
    // Required method
    fn delete(
        &mut self,
        key: Self::Key,
    ) -> impl Future<Output = Result<bool, Self::Error>>;
}

A mutable key-value store that supports deleting values.

Required Methods

fn delete( &mut self, key: Self::Key, ) -> impl Future<Output = Result<bool, Self::Error>>

Delete the value of a key.

Returns true if the key existed and was deleted, false if it did not exist.

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.
