Struct RoundRobin

Source

pub struct RoundRobin<H: Hasher = Sha256> { /* private fields */ }

Expand description

Configuration for round-robin leader election.

Rotates through participants based on (epoch + view) % num_participants. The rotation order can be shuffled at construction using a seed.

Works with any signing scheme.

Implementations§

Source §

impl<H: Hasher> RoundRobin<H>

Source

pub fn shuffled(seed: &[u8]) -> Self

Creates a round-robin config that will shuffle the rotation order based on seed.

The seed is used during Config::build to deterministically shuffle the permutation.
