Trait StorageKey

pub trait StorageKey {
    const KEY: Key;

    // Provided method
    fn key(&self) -> Key { ... }
}

Holds storage key for the type.

Note

The trait is automatically implemented for Packed types via blanket implementation.

Required Associated Constants

const KEY: Key

Storage key of the type.

Provided Methods

fn key(&self) -> Key

Returns the storage 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.
