Struct DaryHeapU64 

pub struct DaryHeapU64 {
    root: u64,
    blocks: Vec<HeapBlock<u64, 8>>,
    len: usize,
    backend: SimdBackend,
}

A cache-line-oriented 8-ary max-heap for large 64-bit heaps. BinaryHeap can be faster for small heaps and monotone replacements.

Fields

root: u64

blocks: Vec<HeapBlock<u64, 8>>

len: usize

backend: SimdBackend
