}

API for querying information about the finalized chain headers.

This API is implemented by runtimes that are receiving messages from this chain, not by this chain’s runtime itself.

Provided Methods

fn best_finalized( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, ) -> Result<Option<HeaderId<Hash, BlockNumber>>, ApiError>

Returns number and hash of the best finalized header known to the bridge module.

fn free_headers_interval( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, ) -> Result<Option<BlockNumber>, ApiError>

Returns free headers interval, if it is configured in the runtime. The caller expects that if his transaction improves best known header at least by the free_headers_interval`, it will be fee-free.

See [pallet_bridge_grandpa::Config::FreeHeadersInterval] for details.

fn synced_headers_grandpa_info( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, ) -> Result<Vec<StoredHeaderGrandpaInfo<Header>>, ApiError>

Returns the justifications accepted in the current block.
