Api for querying onchain state in the test

Provided Methods

fn free_balance( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, account_id: AccountId, ) -> Result<Balance, ApiError>

Api to get the free balance of the given account

fn get_open_channel_for_chain( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, dst_chain_id: ChainId, ) -> Result<Option<ChannelId>, ApiError>

Returns the last open channel for a given domain.

fn verify_proof_and_extract_leaf( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, proof: ConsensusChainMmrLeafProof<NumberFor<Block>, Block::Hash, H256>, ) -> Result<Option<MmrLeaf<NumberFor<Block>, Block::Hash>>, ApiError>

Verify the mmr proof statelessly and extract the state root.
