Struct StrOutputPredicate 

pub struct StrOutputPredicate<P: Predicate<str>>(/* private fields */);

predicates_core::Predicate used by IntoOutputPredicate for Predicate<str>.

Example

use assert_cmd::prelude::*;

use std::process::Command;
use predicates::prelude::*;

Command::cargo_bin("bin_fixture")
    .unwrap()
    .env("stdout", "hello")
    .env("stderr", "world")
    .assert()
    .stderr(predicate::str::diff("world\n"));
