该文件中的Parameter(pub,ParameterCollector)定义了两个结构体,这两个结构体的作用都与收集约束泛型参数有关。 Parameter结构体表示一个泛型参数,并包含了一个pub字段,用来表示参数是否为公共参数。在Rust中,泛型参数可以是公共的(pub标记)或者是私有的。公共参数可以被外部代码访问,私有参数只能在定义它们的模块内部使...

The purpose of thecx: &mut Contextparameter is to pass aWakerinstance to the asynchronous task, e.g., the file system load. ThisWakerallows the asynchronous task to signal that it (or a part of it) is finished, e.g., that the file was loaded from disk. Since the main task knows ...
