pub struct WaitError { /* private fields */ }

An error from failing to wait for a command. Produced by ChildExt.

let mut command = Command::new("echo");
command.arg("puppy doggy");
let displayed: Utf8ProgramAndArgs = (&command).into();
let error = WaitError::new(
    Box::new(displayed),
    std::io::Error::new(
        std::io::ErrorKind::NotFound,
        "File not found (os error 2)"
