Cow in std::borrow - Rust - Learn Rust
The type Cow is a smart pointer providing clone-on-write functionality: it can enclose and provide immutable access to borrowed data, and clone the data lazily when mutation or ownership is required. The type is designed to work with general borrowed data via the Borrow trait.
Cow in std::borrow - Rust - Rust 文档网
Cow 类型是一种智能指针,提供了写时克隆功能:它可以封装并提供对借用数据的不可变访问,并在需要可变的或所有权时懒惰地克隆数据。 该类型旨在通过 Borrow trait 处理常规借用数据。 Cow 实现了 Deref,这意味

Cow 实现了 Clone-on-write 的数据结构,让你可以在需要的时候再获得数据的所有权。Cow 结构是一种使用 enum 根据当前的状态进行分发的经典方案。甚至,你可以用类似的方案取代 trait object 做动态分发,其效率是动态分发的数十倍。

Cow 类型是一个智能指针,提供写入时克隆功能:它可以封装并提供对借用数据的不可变访问,并在需要改变或所有权时延迟克隆数据。 该类型旨在通过 Borrow 特性处理一般借用数据。 Cow 实现了 Deref ,这意味着您可以直接对其封装的数据调用非变异方法。 如果需要变异, to_mut 将获得对所拥有值的可变引用,并在必要时进行克隆。 如果您需要引用计数指针,请注意 Rc::make_mut 和 Arc::make_mut 也可以提供写时克隆功能。 fn abs_all (input: & mut Cow<'_, …

From trait conflicting between `bool` and `Cow<str>`
2024年7月4日 · Rust doesn't allow overlapping implementations, and if std added From<bool> for Cow<'_, str>, then. There would also be Into<Cow<'_, str>> for bool; Then your impl<'a, T: Into<Cow<'_, str>> From<T> for Repr<'a> would apply for T = bool; And this would overlap with your impl From<bool> for Repr<'_>
