Struct sc_finality_grandpa::AuthoritySet

pub struct AuthoritySet<H, N> { /* fields omitted */ }

A set of authorities.

Implementations

impl<H: Eq, N> AuthoritySet<H, N> where
    N: Add<Output = N> + Ord + Clone + Debug,
    H: Clone + Debug, 

pub fn enacts_standard_change<F, E>(
    &self,
    finalized_hash: H,
    finalized_number: N,
    is_descendent_of: &F
) -> Result<Option<bool>, Error<N, E>> where
    F: Fn(&H, &H) -> Result<bool, E>,
    E: Error, 

Check whether the given finalized block number enacts any standard authority set change (without triggering it), ensuring that if there are multiple changes in the same branch, finalizing this block won’t finalize past multiple transitions (i.e. transitions must be finalized in-order). Returns Some(true) if the block being finalized enacts a change that can be immediately applied, Some(false) if the block being finalized enacts a change but it cannot be applied yet since there are other dependent changes, and None if no change is enacted. The given function is_descendent_of should return true if the second hash (target) is a descendent of the first hash (base).
