Struct FinalizedHeaders

Source 
pub struct FinalizedHeaders<'a, Block: BlockT, HP: HeaderProvider<Block>, HS: HeaderSubscription<Block>> { /* private fields */ }
Expand description

Stream of all finalized headers.

Returned headers are guaranteed to be ordered. There are no missing headers (even if some of them lack justification).
