Add tide support

I'm currently doing something like this.

pub async fn not_found(_ctx: Request<AppState>) -> tide::Result {
    let mut buf = Vec::new();
    templates::statuscode404(&mut buf)?;

    Ok(Response::new(StatusCode::NotFound)
        .body(Body::from(buf))
        .set_mime(mime::TEXT_HTML_UTF_8))
}

Here is a trait so it is now easier to use template with tide.

use renderer::Render;

pub async fn not_found_route(_req: Request<AppState>) -> tide::Result {
    let mut res = Response::new(StatusCode::NotFound);
    res.render_html(|o| Ok(templates::notfound(o)?))?;
    Ok(res)
}

pub trait Render {
    fn render<Call>(&mut self, call: Call) -> std::io::Result<()>
    where
        Call: FnOnce(&mut dyn std::io::Write) -> std::io::Result<()>;

    fn render_html<Call>(&mut self, call: Call) -> std::io::Result<()>
    where
        Call: FnOnce(&mut dyn std::io::Write) -> std::io::Result<()>;
}

impl Render for tide::Response {
    fn render<Call>(&mut self, call: Call) -> std::io::Result<()>
    where
        Call: FnOnce(&mut dyn std::io::Write) -> std::io::Result<()>,
    {
        let mut buf = vec![];
        call(&mut buf)?;
        self.set_body(buf);
        Ok(())
    }

    fn render_html<Call>(&mut self, call: Call) -> std::io::Result<()>
    where
        Call: FnOnce(&mut dyn std::io::Write) -> std::io::Result<()>,
    {
        self.render(call)?;
        self.set_content_type(tide::http::mime::HTML);
        Ok(())
    }
}

The tide example is extended in #94

While doing that I discovered that tide uses a Mime type from http-types rather than the mime crate. So I'll do a separate PR providing a feature for that include a feauture for that in #94 (making it easier to test with the example in the same PR).

[kaj]

Merged the example in #94 . The rendering traits can still be moved from the example to the feature, but that can wait for another PR.

[prabirshrestha]

Awesome. Thanks for improving this.

For now I wouldn't go and add it as a feature since the api for tide is changing quite rapidly. Might be can revisit in the next few months once the api are stable.

I already did add a tide013 feature, but that is minimal, it only provides the http-types Mime support through the tide::http reexport.

I'll close this. The minimal feature and example exists, but tide itself has not been updated the last two years, so maybe not the most relevant web framework anymore.
