Struct ethcore::miner::Miner
[−]
[src]
pub struct Miner { pub seals_internally: bool, // some fields omitted }
Keeps track of transactions using priority queue and holds currently mined block. Handles preparing work for "work sealing" or seals "internally" if Engine does not require work.
Fields
seals_internally: bool
Does the node perform internal (without work) sealing.
