pub struct AuthoritySetChanges<N>(_);
Expand description

Tracks historical authority set changes. We store the block numbers for the last block of each authority set, once they have been finalized. These blocks are guaranteed to have a justification unless they were triggered by a forced change.

Implementations§

source§

impl<N: Ord + Clone> AuthoritySetChanges<N>

source

pub fn iter_from( &self, block_number: N ) -> Option<impl Iterator<Item = &(u64, N)>>

Returns an iterator over all historical authority set changes starting at the given block number (excluded). The iterator yields a tuple representing the set id and the block number of the last block in that set.
