Struct sc_network::config::OnDemand [−][src]
Implements the Fetcher trait of the client. Makes it possible for the light client to perform
network requests for some state.
This implementation stores all the requests in a queue. The network, in parallel, is then responsible for pulling elements out of that queue and fulfilling them.
Implementations
impl<B: BlockT> OnDemand<B> where
B::Header: HeaderT, [src]
B::Header: HeaderT,
pub fn new(checker: Arc<dyn FetchChecker<B>>) -> Self[src]
Creates new on-demand service.
pub fn checker(&self) -> &Arc<dyn FetchChecker<B>>[src]
Get checker reference.
