Interface IntoOutputPredicate

src/assert.rs:749–758

Used by [`Assert::stdout`] and [`Assert::stderr`] to convert Self into the needed [`predicates_core::Predicate<[u8]>`]. # Examples ```rust,no_run use assert_cmd::prelude::*; use std::process::Command; use predicates::prelude::*; Command::cargo_bin("bin_fixture") .unwrap() .env("stdout", "hello") .env("stderr", "world") .assert() .stdout(predicate::str::diff("hello\n").from_utf8()); // which c

///     .stdout("hello\n");
/// ```
pub trait IntoOutputPredicate<P>
where
    P: predicates_core::Predicate<[u8]>,
{
    /// The type of the predicate being returned.
    type Predicate;

    /// Convert to a predicate for testing a path.
    fn into_output(self) -> P;
}
