The getheaders message

Fields

version: u32

The protocol version

locator_hashes: Vec<BlockHash>

stop_hash: BlockHash

References the header to stop at, or zero to just fetch the maximum 2000 headers

Implementations

impl GetHeadersMessage

pub fn new( locator_hashes: Vec<BlockHash>, stop_hash: BlockHash ) -> GetHeadersMessage
