fn on_runtime_upgrade() -> Weight

Hook executed when a code change (aka. a “runtime upgrade”) is detected by FRAME.

fn offchain_worker(_n: BlockNumber)

Implementing this function on a pallet allows you to perform long-running tasks that are dispatched as separate threads, and entirely independent of the main wasm runtime.

fn integrity_test()
