Expand description

Abstract type for retrieving block headers and data.

Required Methods§

Source

fn get_header<'life0, 'life1, 'async_trait>( &'life0 self, header_hash: &'life1 BlockHash, ) -> Pin<Box<dyn Future<Output = BlockSourceResult<BlockHeaderData>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns the header for a given hash

Source

fn get_block<'life0, 'life1, 'async_trait>( &'life0 self, header_hash: &'life1 BlockHash, ) -> Pin<Box<dyn Future<Output = BlockSourceResult<Block>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns the block for a given hash.

Source

fn get_block_hash<'life0, 'async_trait>( &'life0 self, height: u32, ) -> Pin<Box<dyn Future<Output = BlockSourceResult<Option<BlockHash>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns hash of block in best-block-chain at height provided.

Source

fn get_best_block<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = BlockSourceResult<(BlockHash, u32)>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns the hash of the best block and, optionally, its height.

When polling a block source, [Poll] implementations may pass the height to get_header to allow for a more efficient lookup.
