Rust 中的库 crate 和普通 crate 有什么区别?

问题描述

在阅读官方书籍时，我偶然发现了包裹和板条箱.要创建一个新的项目"，这是我运行的:

While reading the official book, I stumbled upon packages and crates. To create a new "project", this is what I ran:

$ cargo new my-project
     Created binary (application) `my-project` package
$ ls my-project
Cargo.toml
src
$ ls my-project/src
main.rs

书中陈述如下:

一个包必须包含零个或一个库包，不能更多.它可以包含任意数量的二进制 crate，但必须至少包含一个 crate(库或二进制).

我的疑问是，binary crate 和普通 crate 有什么区别?

My doubt is, what is the difference between binary crates and normal crates?

推荐答案

binary crate 和 library crate 的区别.没有正常"的板条箱.

The difference is between binary crate and library crate. There are no "normal" crates.

• 二进制包是一个可执行程序.

• A binary crate is an executable program.

库包是可重用组件的库，可以包含在另一个库包或二进制包中.

A library crate is a library of reusable components that can be included in another library crate or in a binary crate.
