    NET 9 中的 Alternate Lookup

    NET 9 中的 Alternate Lookup Intro 在 .NET 9 中,为哈希表类引入了一种名为GetAlternateLookup<TKey, TValue, TAlternate>() Alternate Lookup 通过引入AlternateLookup<ReadOnlySpan<char>> 结构,我们可以直接使用ReadOnlySpan<char> 作为键,避免不必要的分配。 static SpanSplitEnumerator<T> Split<T>( this ReadOnlySpan<T> source, T separator) Benchmarking Alternate ); bool Equals(TAlternate alternate, T other); int GetHashCode(TAlternate alternate); 构建我们自己的 alternate lookup 这是一个小示例程序,演示了所有内容如何协同工作。我们有一个以人员对象为索引的字典,每个人员都有一个用于索引的ID。

    震惊!CSS 也能实现碰撞检测?

    不过这里,也并非碰撞检测,我们只需要设置好单个方向的运动动画,并且设置 animation-direction: alternate; 即可! 也就是 animation-direction: alternate; 的简写,表示动画在每个循环中正反交替播放 这样,我们就巧妙的实现了,在视觉上,小球元素移动到最右侧边界时,回弹的效果: 如法炮制 , vertical 3s infinite linear alternate; } @keyframes horizontal { from { left animation: horizontal 2.6s infinite linear alternate, vertical 1.9s infinite linear alternate; } 如此一来,整体的效果就好上了不少,由于整个动画是无限反复进行的,随着时间的推进,整个动画呈现出来的就是无序、随机的运动: 使用 transform 替代 top、left

    我们同时遍历旧fiber的children(wipFiber.alternate)和要协调的元素数组。在此过程中我们忽略掉一些其他的信息之后,其实仅仅关心oldFiber和element。 用hook索引去检查fiber的alternate属性。如果有旧的hook,我们将state从旧的hook复制到新的hook,否则我们将初始化state。 && wipFiber.alternate.hooks && wipFiber.alternate.hooks[hookIndex]; const hook = { state && wipFiber.alternate.hooks && wipFiber.alternate.hooks[hookIndex]; const hook = { state && wipFiber.alternate.hooks && wipFiber.alternate.hooks[hookIndex]; const hook = { state
