Trait relay_substrate_client::ChainWithGrandpa

pub trait ChainWithGrandpa: Chain + ChainWithGrandpaBase {
    type KeyOwnerProof: Decode + TypeInfo + Send;

    const SYNCED_HEADERS_GRANDPA_INFO_METHOD: &'static str;
}

Substrate-based chain that is using direct GRANDPA finality from minimal relay-client point of view.

Keep in mind that parachains are relying on relay chain GRANDPA, so they should not implement this trait.

Required Associated Types

type KeyOwnerProof: Decode + TypeInfo + Send

The type of the key owner proof used by the grandpa engine.

Required Associated Constants

const SYNCED_HEADERS_GRANDPA_INFO_METHOD: &'static str

Name of the runtime API method that is returning the GRANDPA info associated with the headers accepted by the submit_finality_proofs extrinsic in the queried block.

Keep in mind that this method is normally provided by the other chain, which is bridged with this chain.

This trait is not object safe.
