A trait that defines operations for chain selection

Required Methods

fn select_secure_chain(
    &mut self,
    candidates: Vec<Self>
) -> Result<(), ConsensusError>where
    Self: Sized,

Top level API to select between chains during a fork.

fn select_longer_chain(&mut self, candidate: Self) -> Result<(), ConsensusError>where
    Self: Sized,

Selects the longer chain when there’s a short range fork.

fn is_short_range(&self, candidate: &Self) -> Result<bool, ConsensusError>

Checks whether the fork is short range wrt to candidate chain

fn relative_min_window_density(
    &self,
    candidate: &Self
) -> Result<u32, ConsensusError>

Calculates the relate minimum window density wrt to candidate chain.

fn config(&self) -> ConsensusConstants

Constants used for consensus
