Examples

Using with epilogue_macros:

use hyperlane::*;
use hyperlane_macros::*;

#[route("/http_from_stream")]
struct HttpFromStreamTest;

impl ServerHook for HttpFromStreamTest {
    async fn new(_ctx: &Context) -> Self {
        Self
    }

    #[epilogue_macros(
        request_query("test" => request_query_option),
        response_body(&format!("request query: {request_query_option:?}")),
        send,
        http_from_stream(1024)
    )]
    async fn handle(self, ctx: &Context) {}
}

Using with variable name:

use hyperlane::*;
use hyperlane_macros::*;

#[route("/http_from_stream")]
struct HttpFromStreamTest;

impl ServerHook for HttpFromStreamTest {
    async fn new(_ctx: &Context) -> Self {
        Self
    }

    #[epilogue_macros(
        http_from_stream(_request)
    )]
    async fn handle(self, ctx: &Context) {}
}

impl HttpFromStreamTest {
    #[http_from_stream(_request)]
    async fn http_from_stream_with_ref_self(&self, ctx: &Context) {}
}

#[http_from_stream]
async fn standalone_http_from_stream_handler(ctx: &Context) {}
