FetchFullBlockRangeFuture

reth_network_p2p::full_block

Struct FetchFullBlockRangeFuture 

Source 
pub struct FetchFullBlockRangeFuture<Client>
where
    Client: BlockClient,
{ /* private fields */ }
Expand description

A future that downloads a range of full blocks from the network.

This first fetches the headers for the given range using the inner Client. Once the request is complete, it will fetch the bodies for the headers it received.

Once the bodies request completes, the [SealedBlock]s will be assembled and the future will yield the full block range.

The full block range will be returned with falling block numbers, i.e. in descending order.

NOTE: this assumes that bodies responses are returned by the client in the same order as the hash array used to request them.
