pub trait RelaychainStateProvider {

Expand description

This exposes the RelayChainState to other runtime modules.

Enables parachains to read relay chain state via state proofs.

Required Methods§

source

fn current_relay_chain_state() -> RelayChainState

May be called by any runtime module to obtain the current state of the relay chain.

NOTE: This is not guaranteed to return monotonically increasing relay parents.

Provided Methods§

source

fn set_current_relay_chain_state(_state: RelayChainState)

Utility function only to be used in benchmarking scenarios, to be implemented optionally, else a noop.

It allows for setting a custom RelayChainState.

Object Safety§

This trait is not object safe.
