Expand description

Server trait implementation for the MmrApi RPC API.

Required Methods§

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.

Generate MMR proof for the given leaf indices.

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

Returns the leaves and a proof for these leaves (compact encoding, i.e. hash of the leaves). Both parameters are SCALE-encoded. The order of entries in the leaves field of the returned struct is the same as the order of the entries in leaf_indices supplied

Provided Methods§

Collects all the methods and subscriptions defined in the trait and adds them into a single RpcModule.
