Struct DaryHeapU32 

pub struct DaryHeapU32 {
    root: u32,
    blocks: Vec<HeapBlock<u32, 16>>,
    len: usize,
    backend: SimdBackend,
}

A cache-line-oriented 16-ary max-heap for medium-to-large 32-bit heaps. BinaryHeap can be faster for small heaps and monotone replacements.

Fields

root: u32

blocks: Vec<HeapBlock<u32, 16>>

len: usize

backend: SimdBackend
