Struct sc_network_sync::block_request_handler::FullBlockDownloader

pub struct FullBlockDownloader { /* private fields */ }

Expand description

The full block downloader implementation of `BlockDownloader.

Trait Implementations§

impl<B: BlockT> BlockDownloader<B> for FullBlockDownloader

fn download_blocks<'life0, 'async_trait>( &'life0 self, who: PeerId, request: BlockRequest<B> ) -> Pin<Box<dyn Future<Output = Result<Result<Vec<u8>, RequestFailure>, Canceled>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait,

Performs the protocol specific sequence to fetch the blocks from the peer. Output: if the download succeeds, the response is a Vec<u8> which is in a format specific to the protocol implementation. The block data can be extracted from this response using BlockDownloader::block_response_into_blocks.

fn block_response_into_blocks( &self, request: &BlockRequest<B>, response: Vec<u8> ) -> Result<Vec<BlockData<B>>, BlockResponseError>

Parses the protocol specific response to retrieve the block data.
