Trait assert_cmd::IntoCodePredicate

pub trait IntoCodePredicate<P> where
    P: Predicate<i32>, {
    fn into_code(self) -> P;
}

Used by Assert::code to convert Self into the needed Predicate<i32>.

Examples

use assert_cmd::prelude::*;

use std::process::Command;

Command::main_binary()
    .unwrap()
    .env("exit", "42")
    .assert()
    .code(42);
// which is equivalent to
Command::main_binary()
    .unwrap()
    .env("exit", "42")
    .assert()
    .code(predicates::ord::eq(42));

Required Methods

fn into_code(self) -> P

Convert to a predicate for testing a program's exit code.
