pub trait StorageKey {
    const KEY: u32;

    // Provided method
    fn key(&self) -> u32 { ... }
}

Holds storage key for the type.

Note

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

Required Associated Constants

const KEY: u32

Storage key of the type.

Provided Methods

fn key(&self) -> u32

Returns the storage key.

Object Safety

This trait is not object safe.
