使用anyhow::Error返回自定义错误类型的更简单方法？

use std::error::Error;
use anyhow::{anyhow, Context, Error};

#[derive(Debug)]
struct CustomError {
    message: String,
}

impl std::error::Error for CustomError {}

impl std::fmt::Display for CustomError {
    fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
        write!(f, "{}", self.message)
    }
}

impl anyhow::Context for CustomError {}

impl From<CustomError> for Error {
    fn from(error: CustomError) -> Self {
        anyhow!(error)
    }
}

fn main() -> Result<(), Error> {
    let custom_error = CustomError {
        message: "Custom error message".to_string(),
    };

    Err(custom_error.into())
}
