Struct assert_fs::assert::StrPathPredicate

pub struct StrPathPredicate<P: Predicate<str>>(_);

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

Example

use assert_fs::prelude::*;
use predicates::prelude::*;

let temp = assert_fs::TempDir::new().unwrap();
let input_file = temp.child("foo.txt");
input_file.touch().unwrap();

// ... do something with input_file ...

input_file.assert(predicate::str::is_empty()); // Uses StrPathPredicate

temp.close().unwrap();
