async/awaitfeature of Rust. We take a detailed look at how async/await works in Rust, including the design of theFuturetrait, the state machine transformation, andpinning. We then add basic support for async/aw
You are viewing the a post of the first edition of “Writing an OS in Rust”, which is no longer updated. You can find the second edition here. In the previous post we created a minimal multiboot kernel. It just prints OK and hangs. The goal is to extend it and call 64-bit Rust...

Rust Rust中的Async /Await Rust语言以async/await的形式为协作式多任务提供了支持。 在探讨什么是async/await及其如何工作之前,我们需要了解futures和异步编程如何在Rust中工作。 Futures Future代表一个可能尚不可用值。 例如,这可能是由另一个任务计算的整数,也可以是从网络下载的文件。 Future无需等到该值可用时,...

As a side project, I decided to write my own file system in Rust as I’m learning the language. Some aspects are inspired by ext4 [2] (and family), and in this section, you will learn more about it. The file system uses FUSE [3], and the disk is represented as a regular file...
// `newAdder` returns a closure that makes use of the free variables `a` and `b`:letnewAdder=fn(a,b){fn(c){a+b+c};};// This constructs a new `adder` function:letadder=newAdder(1,2);adder(8);// => 11 Yes, we'llcompileall of that tobytecodeand execute it in astack-ba...

Opening a file is performed using the fopen() function defined in the stdio.h header file. The syntax for opening a file in standard I/O is: ptr = fopen("fileopen","mode"); For example, fopen("E:\\cprogram\\newprogram.txt","w"); fopen("E:\\cprogram\\oldprogram.bin","rb"...
