Trait polars_core::prelude::VecHash

pub trait VecHash {
    fn vec_hash(&self, _random_state: RandomState) -> AlignedVec<u64> { ... }
    fn vec_hash_combine(&self, _random_state: RandomState, _hashes: &mut [u64]) { ... }
}

Provided methods

fn vec_hash(&self, _random_state: RandomState) -> AlignedVec<u64>

Compute the hash for all values in the array.

This currently only works with the AHash RandomState hasher builder.

fn vec_hash_combine(&self, _random_state: RandomState, _hashes: &mut [u64])
