Rust 中的库 crate 和普通 crate 有什么区别? [英] What is the difference between library crates and normal crates in Rust?

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).

A package must contain zero or one library crates, and no more. It can contain as many binary crates as you’d like, but it must contain at least one crate (either library or binary).

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.
