Struct solana_gossip::weighted_shuffle::WeightedShuffle

source · [−]

pub struct WeightedShuffle<T> { /* private fields */ }

Expand description

Implements an iterator where indices are shuffled according to their weights:

Returned indices are unique in the range [0, weights.len()).
Higher weighted indices tend to appear earlier proportional to their weight.
Zero weighted indices are shuffled and appear only at the end, after non-zero weighted indices.
