Struct assert_cmd::assert::InCodePredicate

pub struct InCodePredicate(_);

Keep predicates concrete Predicates out of our public API. predicates_core::Predicate used by IntoCodePredicate for iterables of codes.

Example

use assert_cmd::prelude::*;

use std::process::Command;

Command::cargo_bin("bin_fixture")
    .unwrap()
    .env("exit", "42")
    .assert()
    .code(&[2, 42] as &[i32]);
