Attribute Macro request_error 

#[request_error]

Registers a function as a request error hook.

This attribute macro registers the decorated function to handle request errors that occur during request processing. This macro requires the #[hyperlane(server: Server)] macro to be used to define the server instance.

Note

If an order parameter is not specified, the hook will have a higher priority than hooks with a specified order.

Usage

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

#[request_error]
#[request_error(1)]
#[request_error("2")]
struct RequestErrorHook;

impl ServerHook for RequestErrorHook {
    async fn new(_: &mut Stream, _: &mut Context) -> Self {
        Self
    }

    #[epilogue_macros(response_body("request_error"), send)]
    async fn handle(self, stream: &mut Stream, ctx: &mut Context) -> Status { Status::Continue }
}

Dependencies

This macro depends on the #[hyperlane(server: Server)] macro to define the server instance.
