std::format for application/x-www-form-urlencoded

[octaltree]

Describe the feature you'd like
I want yew::format::urlencoded::UrlEncoded(T) format request to application/x-www-form-urlencoded and parse response.

Is your feature request related to a problem? Please describe. (Optional)
I don't know why this feature is not implemented.

Describe alternatives you've considered (Optional)
For my app, I implemented this with serde_urlencoded.

pub struct UrlEncoded<T>(T);

impl<'a, T> Into<Result<String, anyhow::Error>> for UrlEncoded<&'a T>
where
    T: serde::Serialize
{
    fn into(self) -> Result<String, anyhow::Error> { Ok(serde_urlencoded::to_string(self.0)?) }
}

#[derive(Debug, PartialEq, Clone, Serialize)]
pub struct Request {
    ident: String,
    password: String
}

#[test]
fn encode_request() {
    let req = Request {
        ident: "foo@example.com".into(),
        password: "0000".into()
    };
    let rb: Result<String, anyhow::Error> = UrlEncoded(&req).into();
    let b = rb.expect("failure serialize");
    assert_eq!("ident=foo%40example.com&password=0000", b);
}

Additional context (Optional)

Questionnaire

• I'm interested in implementing this myself but don't know where to start
• I would like to add this feature
• I don't have time to add this right now, but maybe later

yew::format was removed in #1842 so this issue should be closed.
