Struct cradle::Exit

pub struct Exit(pub ExitStatus);

See the CmdOutput implementation for Exit below.

Trait Implementations

impl CmdOutput for Exit

Using Exit as the return type for cmd! allows to retrieve the ExitStatus of the child process:

use cradle::*;

let Exit(status) = cmd!(%"echo foo");
assert!(status.success());

Also, when using Exit, non-zero exit codes won’t result in neither a panic nor a std::result::Result::Err:

use cradle::*;

let Exit(status) = cmd!("false");
assert_eq!(status.code(), Some(1));
let result: Result<Exit, cradle::Error> = cmd_result!("false");
assert!(result.is_ok());
assert_eq!(result.unwrap().0.code(), Some(1));

Also see the section about error handling in the module documentation.
