Trait GetKeyValue 

pub trait GetKeyValue<T>: CollectionRef + KeyedRef {
    // Required method
    fn get_key_value(
        &self,
        key: T,
    ) -> Option<(Self::KeyRef<'_>, Self::ItemRef<'_>)>;
}

Queryable map.

Required Methods

fn get_key_value(&self, key: T) -> Option<(Self::KeyRef<'_>, Self::ItemRef<'_>)>

Returns the key-value pair matching the given key.

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.
