Struct assert_cmd::assert::EqCodePredicate

pub struct EqCodePredicate(_);

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

Example

use assert_cmd::prelude::*;

use std::process::Command;

Command::cargo_bin("bin_fixture")
    .unwrap()
    .env("exit", "42")
    .assert()
    .code(42);
