HashSort

gnu_sort::hash_sort

Struct HashSort

pub struct HashSort;

Expand description

Hash-based random sort with O(n) complexity

Implementations§

impl HashSort

pub fn hash_sort<T: Clone>( lines: &mut [T], get_key: impl Fn(&T) -> &[u8] + Sync, )

Hash-based grouping with zero-copy shuffling O(n) complexity instead of O(n log n)

pub fn parallel_hash_sort<T: Clone + Send + Sync>( lines: &mut [T], get_key: impl Fn(&T) -> &[u8] + Sync, )

BREAKTHROUGH: Parallel hash-based random sort for massive datasets

pub fn streaming_random_sort<R, W>( _reader: R, _writer: W, _memory_limit_mb: usize, ) -> Result<()>
where R: BufRead, W: Write,

BREAKTHROUGH: Streaming random sort for gigantic files
