Struct StrPathPredicate

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

Available on crate feature assert only.

Adapter used by IntoUtf8PathPredicate for Predicate<str> instances, such as those in [predicates::str].

Example

use camino_tempfile_ext::prelude::*;
use predicates::prelude::*;

let temp = Utf8TempDir::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();
