带有库和二进制文件的 Rust 包? [英] Rust package with both a library and a binary?

问题描述

我想制作一个 Rust 包，其中包含一个可重用的库(大部分程序在其中实现)，以及一个使用它的可执行文件.

I would like to make a Rust package that contains both a reusable library (where most of the program is implemented), and also an executable that uses it.

假设我没有混淆 Rust 模块系统中的任何语义，我的 Cargo.toml 文件应该是什么样的?

Assuming I have not confused any semantics in the Rust module system, what should my Cargo.toml file look like?

推荐答案

Tok:tmp doug$ du -a

8   ./Cargo.toml
8   ./src/bin.rs
8   ./src/lib.rs
16  ./src

Cargo.toml:

Cargo.toml:

[package]
name = "mything"
version = "0.0.1"
authors = ["me <[e-mail]>"]

[lib]
name = "mylib"
path = "src/lib.rs"

[[bin]]
name = "mybin"
path = "src/bin.rs"

src/lib.rs:

src/lib.rs:

pub fn test() {
    println!("Test");
}

src/bin.rs:

src/bin.rs:

extern crate mylib; // not needed since Rust edition 2018

use mylib::test;

pub fn main() {
    test();
}
