Function bridge_runtime_common::messages_benchmarking::prepare_message_proof_from_grandpa_chain

pub fn prepare_message_proof_from_grandpa_chain<R, FI, MI>(
    params: MessageProofParams<LaneIdOf<R, MI>>,
    message_generator: impl Fn(usize) -> MessagePayload,
) -> (FromBridgedChainMessagesProof<HashOf<BridgedChainOf<R, MI>>, LaneIdOf<R, MI>>, Weight)

Prepare proof of messages for the receive_messages_proof call.

In addition to returning valid messages proof, environment is prepared to verify this message proof.

This method is intended to be used when benchmarking pallet, linked to the chain that uses GRANDPA finality. For parachains, please use the prepare_message_proof_from_parachain function.
