Interface IntoCodePredicate

src/assert.rs:555–564

Used by [`Assert::code`] to convert `Self` into the needed [`predicates_core::Predicate `]. # Examples ```rust,no_run use assert_cmd::prelude::*; use std::process::Command; use predicates::prelude::*; Command::cargo_bin("bin_fixture") .unwrap() .env("exit", "42") .assert() .code(predicate::eq(42)); // which can be shortened to: Command::cargo_bin("bin_fixture") .unwrap() .env("exit", "42"

///     .code(42);
/// ```
pub trait IntoCodePredicate<P>
where
    P: predicates_core::Predicate<i32>,
{
    /// The type of the predicate being returned.
    type Predicate;

    /// Convert to a predicate for testing a program's exit code.
    fn into_code(self) -> P;
}
