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.

The following example shows the most basic usage of class log:

Use log::loglevel;//Log Level

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 () {

Odysseus had participated in the famous Trojan War, known for his bravery and resourcefulness in the war, and in order to win the war, he designed and made the famous "Trojan Horse" (later in the West became a "gift for the destruction of the enemy" synonymous). After the destruction of Troy, he experienced many risks on his way home, and Homer's Odyssey was an account of the adventur
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.

In the recycler system, all classes (CAN, bottle, and

Referential Integrity)
Make sure that the foreign key of one table corresponds to the primary key of the other 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
