16.2 使用消息传递在线程之间传输数据 确保安全并发的一种日益流行的方法是消息传递(message passing),其中线程或参与者通过相互发送包含数据的消息进行通信。这是Go语言文档中的一句口号:“不要通过共享内存进行交流;相反,应该通过交流来分享记忆。(Do not communicate by sharing memory; instead, share memory by comm...
If you want to share data between different parts of your Rust program, you can use several alternatives to global variables. These include passing data as function arguments, returning data from functions, using data structures like structs and enums, and using concurrency primitives like channels...

对于以JavaScript为主的Node.js开发者来说,你可能不太熟悉类似于“std::wx::y”或“&xyz”之类的表述,但是没关系,我会详细解释。 与JavaScript和Node.js相比,Rust是一门较为低级的语言。这意味着,你需要熟悉计算机的工作原理,才能真正理解Rust。而Node.js更为高级,通常接触不到这些表述。
Passing an array requires both a pointer and the length of the array. The array is implicitly converted to a pointer to the first element, of type Ptr{UInt32}. The type Csize is the Julia equivalent of size_t. We also enforce the function argument type to Array{UInt32}, which is the...
So, a pure function may modify a local variable allocated on the stack, but not a mutable reference that it takes as an argument. A pure function may only call other pure functions, not general functions.An example of a pure function:...

Moving is not limited to passing arguments. You can move to a variable. You can move to the “return value”—or from the return value—or from a variable, or a function argument, for that matter. Basically, it’s everywhere where there is an explicit or implicit assignment. ...
