使用core::cmp::Reverse 对原生的元素使用core::cmp::Reverse进行封装处理,官方示例如下 use std::collections::BinaryHeap; use std::cmp::Reverse; let mut heap = BinaryHeap::new(); // Wrap values in `Reverse` heap.push(Reverse(1)); hea
usestd::collections::BinaryHeap;letheap =BinaryHeap::from([1,5,2]); Min-heap core::cmp::Reverse或自定义的Ord实现可用于使BinaryHeap成为min-heap。这使得heap.pop()返回最小值而不是最大值。 usestd::collections::BinaryHeap;usestd::cmp::Reverse;letmutheap =BinaryHeap::new();// Wrap values...
BinaryHeap数据结构的最大特点是在我们使用push函数往堆中添加值的时候,一旦输入一个较大的值,它会同当前堆中的其他值比较,然后不断“上浮”。 因此源码解读的重点就在于push函数的实现: 我们先来看BinaryHeap本身的数据结构: #[stable(feature = "rust1", since = "1.0.0")] pub struct BinaryHeap<T> { ...

BinaryHeap 中,并且不会导致未定义的行为。 这可能包括 panics、不正确的结果、中止、内存泄漏和未中止。只要元素在堆中时如上所述没有改变它们的相对顺序,BinaryHeap 的API 就保证堆不,变体,保持不变,即它的方法都按照文档的方式运行。例如,如果一个方法被记录为按排序顺序迭代,那么只要堆中的元素没有改变顺序,...
Rust提供的优先队列是基于二叉最大堆实现的 fn testBinaryHeap(){ use std::collections::BinaryHeap; let mut heap = BinaryHeap::new(); let arr = [93,80,48,53,72,30,18,36,15,35,45]; for &i in arr.it ...
