how can we tell if ArcSwap is better than rwlock? is there any measurement?
if it's way better than rwlock, why not replace all the rwlock at once in a separate PR then?

ArcSwap is faster, becasue its lockless(just like std Atomic). However it not a replacement of Rwlock. It depends on use case. Only stateless data structure can use ArcSwap, like String, number, or struct made up of these types, or structs those dont have interior mutability

i mean it's better to have some measurement (or the official benchmark result) along with it

+    /// support udp or not
+    fn handle_udp(&self) -> bool;
+    async fn listen_tcp(&self) -> anyhow::Result<()>;
+    async fn listen_udp(&self) -> anyhow::Result<()>;


why do we prefer anyhow::Result over std::io::Result?

@hsqStephenZhang Asked this question, I answer here for convience.
Because std::io::Error just cannot cover all error cases!
There are many errors are not io::Error but converted into io Error.
Inbound UDP not support for a start:

clash-rs/clash_lib/src/proxy/http/inbound/mod.rs

Line 73 in e2c9c86

Err(io::Error::new(io::ErrorKind::Other, "unsupported"))

In future there will be more inbounds, tun, tuic, shadowsocks. They may occurs IncorrectConfig/CertificateInvalid/TunDeviceCannotBeCreated which are not io::Error

then why not define more robust error type with thiserror?

Technically speaking，when we define a Error for a trait, We cannot acknowledge ALL the possible specific Error of the trait's all implementations.
If we have to do it(by using thiserror). The definition of Error might be

enum Error { HttpInboundError(inbound::http::Error), SocksInboundError(inbound::socks::Error), TproxyInboundError(inbound::tproxy::Error), ...... }

I dont think it's different from anyhow

By the way, I would like use #717 solution if it's merged into master. But for now using anyhow isn't so bad.

Just as tolnay said in thiserror README

Use thiserror if you care about designing your own dedicated error type(s) so that the caller receives exactly the information that you choose in the event of failure.

In our case, the caller of InboundHandler (which is inbound manager) doesn't care about the type of error at all. It just print the error into logs

fair enough, anyhow is ok for us at the current stage.
