pub struct USimpleError {
    pub code: i32,
    pub message: String,
}

A simple error type with an exit code and a message that implements UError.

use uucore::error::{UResult, USimpleError};
let err = USimpleError { code: 1, message: "error!".into()};
let res: UResult<()> = Err(err.into());
// or using the `new` method:
let res: UResult<()> = Err(USimpleError::new(1, "error!"));

Fields

code: i32

Exit code of the error.

message: String

Error message.
