Trait StringStoreKey 

pub trait StringStoreKey:
    Clone

    + 'static {
    // Required methods
    fn serialize_key(&self) -> String;
    fn deserialize_key(key: &str) -> Option<Self>;
}

Indicates, that a key can be serialized as a String.

Some Store implementations need to internally store keys as a String.

These implementations need to restrict their key type to StringStoreKey.

Caution

In the case of StringStoreKey, it is important that the String representation of the key has the same ordering as the actual keys. This is relevant for OrderedStores.

Required Methods

fn serialize_key(&self) -> String

fn deserialize_key(key: &str) -> Option<Self>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
