Disabling "remove dot segments" behavior

[jwodder]

I have a use-case where I need to be able to construct URLs that end in …/. or …/..¹; however, the url crate insists on removing dot segments no matter what API I go through, even when the dots are percent-escaped, e.g.:

fn main() {
    let url = url::Url::parse("https://example.com/path/%2e%2e").unwrap();
    // Prints "https://example.com/":
    println!("{url}");
}

Is there currently a method to construct a URL like this using this crate? If not, could such a method be added?

Footnotes

1. Specifically, this is for manipulating GitHub labels via the GitHub REST API; if a user names a label with dot or dot-dot, the URL ends up with dots at the end. ↩

This replacement is mandated by the URL standard, so I'd be slightly surprised if the server side doesn't parse the URLs in a similar way.
Have a look at whether encoding the % sign works, so instead of %2e use %252e

use url::Url;

fn main() {
    let bs: &str = "https://example.org/path_to_replace";
    let mut base = Url::parse(bs).unwrap();
    base.path_segments_mut().unwrap().pop().push("%2e%2e");
    println!("{:?}", base); // prints path: "/%252e%252e"
}

@valenting Testing GitHub's REST API via curl, curl https://api.github.com/repos/jwodder/test/labels/.. and …/labels/%252e%252e both result in 404; only …/labels/%2e%2e works.
