I want to know a struct that implements std::io::Write ; 我想知道一个实现std::io::Write ; is it described in some document? 它是在某些文件中描述的吗？

1 个解决方案

When you lookup the API for std you can search for your trait there (eg std::io::Write ). 当您查找std的API时，您可以在那里搜索您的特征（例如std::io::Write ）。

When you scroll down to the section " Implementors " you will see all structs/enums that implement that trait in std . 当您向下滚动到“ 实现者 ”部分时，您将看到在std中实现该特征的所有结构/枚举。

To get a better overview, you can use the + or - keys to collapse all sections and have a nice overview, eg 为了获得更好的概述，您可以使用+或-键折叠所有部分并获得一个很好的概述，例如
