The macro usage scope in Rust 1.7.0 contains three scenarios:The first case is that the macro is defined in the current file. This file may be the default module for crate, or it may be a random module.Another scenario is that the macro is defined in the current crate. But not in the current file, but in other module modules.The third case is that the macro is defined in other

. In this example, the memory space will always exist throughout the app lifecycle, so there is no problem. But in real-world scenarios, we need to manage our space like creating wooden boxes and shapes, encapsulate them in standard Cocoa objects, and then manage the lifecycle of Chipmunk objects. Figure 11.1 shows the dropped wooden case. Listing 11.3 uses physics to model dropped wooden boxes 1 #import "ViewController.h" 2 #import 3 #import "chipmunk.h" 4 5 @interface

Rust provides a mechanism for code encapsulation. Relatively independent module modules can be created by crate (equivalent to the package in Java), which encapsulates functional functions that can be reused. When you create your own Lib library or when you want to use a Third-party library (which is some crate) you need to refer the module modules in these libraries to the current environment. Rust provide

: Level filters of the logging Framework Pub enum Loglevelfilter {off , Error, Warn, Info, Debug, Trace, } The following example shows the most basic usage of class log: #[macro_use] extern crate log; Use log::loglevel;//Log Level fn main () { log_lever_fn (); } fn LOG_LEVER_FN () {Let data= ("Forty-two"); Let private_data= "private"; log! (Loglevel::error, "Received errors:{},{}", data.0,data.1); log! (

Log4rs is a highly configurable log library implemented by rust, which is configured in a flexible and relatively rich way to meet most of the project needs. GitHub Address: Https://github.com/sfackler/log4rs. Usage examples Let's first give a simple example, and you can see from this example that log4rs is very flexible to log configuration: #[macro_use] extern crate log; extern crate log4rs; fn Main () {

Simplelog--a Simple and Easy-to-use logging facility for Rust ' s log crate. The goal of Simplelog is not to provide a very rich feature, nor to provide the best logging solution, but to provide easy-to-use log solutions for small and medium sized projects.Simplelog does not aim to provide a rich set of features, nor to provide the best logging solution. It aims to being a maintainable, easy to integrate facility for small to medium sized Mewhat lacki

relationship is the relationship from the descendant class to its ancestor class. Generalized relationships can take place in several stages, which allows you to model complex, multilevel inherited hierarchies. Generally, features are in the upper part of the hierarchy, while special features are in the lower part. That is to say, you can use generalized relationships to create special models for general concepts. Example In the recycler system, all classes (CAN, bottle, and

Use the Rust standard library std Compile the source file histd. rs: fn main() {println!("Hi Rust!

The file size is 1,389,884 bytes, about 1.32 MB, which is quite large! Vro devices are almost unacceptable. This is an executable file generated by static compilation without additio

that data must conform to, which is divided into three main categories: Solid Integrity (entity Integrity) Specifies that a row of the table (that is, each record) is the only entity in the table. Entity integrity is implemented through the primary key of the table.

This looks like a very small problem, if we are in. NET, it is easy to use System.DateTime.Now directly to get to the current time, but also to perform a variety of different calculations or outputs. But such a problem, in rust, still took me some time. Of course, I think this kind of toss-up also has some benefits, from which we can better understand some of rust's internal principles. First, let's see what we can do. Rust default comes with the STD library, there is no time-based function, if

during program compilation, but does little work during runtime. Because most system programming languages lack Memory Security at runtime, Rust tries its best to ensure that the Code is no problem at runtime after compilation. Although BEAM ensures the memory security during runtime, sometimes the overhead becomes abnormal and complex, so Rust chooses to compile. Rust's core language feature is designed to be as concise as possible. For example, Rust often builds lightweight green threads (sim
