Module classifier 

User-Agent http layer support

Example

use rama_http::{
    Request, Response, StatusCode, service::client::HttpClientExt,
    service::web::response::IntoResponse,
};
use rama_ua::{
    PlatformKind, UserAgent, UserAgentInfo, UserAgentKind,
    layer::classifier::UserAgentClassifierLayer,
};
use rama_core::{extensions::ExtensionsRef, Layer, service::service_fn};
use std::convert::Infallible;

const UA: &str = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/124.0.0.0 Safari/537.36 Edg/124.0.2478.67";

async fn handle(req: Request) -> Result<Response, Infallible> {
    let ua: &UserAgent = req.extensions().get().unwrap();

    assert_eq!(ua.header_str(), UA);
    assert_eq!(ua.info(), Some(UserAgentInfo{ kind: UserAgentKind::Chromium, version: Some(124) }));
    assert_eq!(ua.platform(), Some(PlatformKind::Windows));

    Ok(StatusCode::OK.into_response())
}

let service = UserAgentClassifierLayer::new().into_layer(service_fn(handle));

let _ = service
    .get("http://www.example.com")
    .typed_header(rama_http::headers::UserAgent::from_static(UA))
    .send()
    .await
    .unwrap();
