as-result

Rust crate which provides the AsResult<T, E> and IntoResult<T, E> traits.

Supported Types

By default, the following types from the standard library have implementations of these traits:

• std::process::ExitStatus implemented for std::io::Result<()>
• std::process::Output implemented for std::io::Result<std::process::Output>

Example

Common when spawning commands is the desire to convert the exit status into a result:

use as_result::*;
use std::process::Command;

Command::new("/bin/echo")
    .arg("hello world")
    .status()
    .and_then(IntoResult::into_result)
    .unwrap();

Command::new("/bin/echo")
    .arg("hello world")
    .status()
    .unwrap()
    .into_result()
    .unwrap();

Command::new("/bin/echo")
    .arg("hello world")
    .status()
    .map_result()
    .unwrap()
