即使 src/main.rs 可用，cargo 也不会构建

Question

我正在尝试使用 cargo build 进行构建。以下是项目结构

tree
.
├── Cargo.toml
└── src
    └── main.rs

Cargo.toml的内容

[package]
name = "server"
version = "0.1.0"
authors = ["Lokanath Mohanty <lokanath.mohanty@adcolony.com>"]
edition = "2018"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]

src/main.rs

的内容

use std::io::{ErrorKind, Read, Write};
use std::net::TcpListener;
use std::sync::mpsc;
use std::thread;
use std::time::Duration;

const LOCAL_IP: &str = "127.0.0.1:6001";
const MSG_SIZE: usize = 32;


fn main() {
    ...
}

我收到以下错误 -

error: failed to parse manifest at `/home/debashishc/Downloads/Cargo.toml`

Caused by:
  no targets specified in the manifest
  either src/lib.rs, src/main.rs, a [lib] section, or [[bin]] section must be present

Answer 1

Cargo 寻找并尝试parse Cargo.toml in parent directories, because it checks whether your crate is part of a larger workspace。

从父目录中删除损坏的 Cargo.toml。或者，将您的板条箱 Cargo.toml 设为工作区以阻止货物进一步搜索。

即使 src/main.rs 可用，cargo 也不会构建

cargo would not build even when src/main.rs is available
