Struct assert_cmd::assert::BytesContentOutputPredicate

pub struct BytesContentOutputPredicate(/* private fields */);

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

Example

use assert_cmd::prelude::*;

use std::process::Command;

Command::cargo_bin("bin_fixture")
    .unwrap()
    .env("stdout", "hello")
    .env("stderr", "world")
    .assert()
    .stderr(b"world\n" as &[u8]);
