Source§impl HashPartitioner
impl HashPartitioner
Sourcepub fn new(num_partitions: usize, seed: u64) -> Self
pub fn new(num_partitions: usize, seed: u64) -> Self
Creates a new hash partitioner with the given number of partitions and seed.
Sourcepub fn hash_to_partition(&self, hash: u64) -> usize
pub fn hash_to_partition(&self, hash: u64) -> usize
Converts a hash to a partition. It is guaranteed that the output is in the range [0, n_partitions), and that independent HashPartitioners that we initialized with the same num_partitions and seed return the same partition.
