Make DisplaySafeUrlRef Copy and other minor PR follow-ups (#13683) 
This PR implements a few review follow-ups from #13560. In particular,
it
* Makes `DisplaySafeUrlRef` implement `Copy` so that it can be passed by
value.
* Updates `to_string_with_credentials` methods with
`displayable_with_credentials`, returning an `impl Display` instead of
`String` for greater flexibility.
* Updates the `DisplaySafeUrl` and `DisplaySafeUrlRef` `Debug`
implementations to match the underlying `Url` `Debug` implementation
(with the exception that credentials are masked).
* Replaces an unnecessary `DisplaySafeUrl::from(Url::from_file_path`
with `DisplaySafeUrl::from_file_path`

Dependency specifiers (PEP 508) in Rust

Crates.io PyPI

A library for dependency specifiers, previously known as PEP 508.

Usage

use std::str::FromStr;
use pep508_rs::Requirement;

let marker = r#"requests [security,tests] >= 2.8.1, == 2.8.* ; python_version > "3.8""#;
let dependency_specification = Requirement::from_str(marker).unwrap();
assert_eq!(dependency_specification.name, "requests");
assert_eq!(dependency_specification.extras, Some(vec!["security".to_string(), "tests".to_string()]));

Markers

Markers allow you to install dependencies only in specific environments (python version, operating system, architecture, etc.) or when a specific feature is activated. E.g., you can say importlib-metadata ; python_version < "3.8" or itsdangerous (>=1.1.0) ; extra == 'security'. Unfortunately, the marker grammar has some oversights (e.g. https://github.com/pypa/packaging.python.org/pull/1181) and the design of comparisons (PEP 440 comparisons with lexicographic fallback) leads to confusing outcomes. This implementation tries to carefully validate everything and emit warnings whenever bogus comparisons with unintended semantics are made.
