Subcoin API.

Provided Methods

fn execute_block_without_state_root_check( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, block: Block, ) -> Result<(), ApiError>

Same as the original execute_block() with the removal of state_root check in the final_checks().

fn finalize_block_without_checks( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, header: Block::Header, ) -> Result<(), ApiError>

Finalize block without checking the extrinsics_root and state_root.

fn coins_count( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, ) -> Result<u64, ApiError>

Returns the number of total coins (i.e., the size of UTXO set).

fn get_utxos( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, outpoints: Vec<OutPoint>, ) -> Result<Vec<Option<Coin>>, ApiError>

Query UTXOs by outpoints.

Returns a vector of the same length as the input, with Some(Coin) for UTXOs that exist and None for those that don’t.
