MMR RPC methods.

Required methods

fn generate_proof(
    &self,
    leaf_index: u64,
    at: Option<BlockHash>
) -> Result<LeafProof<BlockHash>>

Generate MMR proof for given leaf index.

This method calls into a runtime with MMR pallet included and attempts to generate MMR proof for leaf at given leaf_index. Optionally, a block hash at which the runtime should be queried can be specified.

Returns the (full) leaf itself and a proof for this leaf (compact encoding, i.e. hash of the leaf). Both parameters are SCALE-encoded.

Provided methods

fn to_delegate<M: Metadata>(self) -> IoDelegate<Self, M> where
    BlockHash: Send + Sync + 'static + Serialize + DeserializeOwned, 

Create an IoDelegate, wiring rpc calls to the trait methods.
