Description
Is it possible for a handler to be stuck during the write_all phase of a response? Take the code below, if conn.write_all was writing a large buffer or over a slow connection, and the client closed the connection.
Would the handler be stuck trying to write_all forever?
impl<'b, T, const N: usize> Handler<'b, T, N> for HttpHandler
where
T: Read + Write,
T::Error: Send + Sync + std::error::Error + 'static,
{
type Error = anyhow::Error;
async fn handle(&self, conn: &mut Connection<'b, T, N>) -> Result<(), Self::Error> {
let headers = conn.headers()?;
if !matches!(headers.method, Some(Method::Get)) {
conn.initiate_response(405, Some("Method Not Allowed"), &[])
.await?;
} else if !matches!(headers.path, Some("/")) {
conn.initiate_response(404, Some("Not Found"), &[]).await?;
} else {
conn.initiate_response(200, Some("OK"), &[("Content-Type", "text/plain")])
.await?;
conn.write_all(b"Hello world!").await?;
}
Ok(())
}
