You may want to replace the SimpleLogger with the env_logger crate, as they appear to do roughly the same thing.

Hello!
I'm new to Rust and this example (load balancer) is very interesting for me.

Can you tell me if I'm correct:
https://github.com/NicolasLM/nucleon/blob/master/src/tcplb.rs#L92
and
https://github.com/NicolasLM/nucleon/blob/master/src/tcplb.rs#L607
are duplicating registering interest about writeable?

So this register or this register can be removed?

Got your reference from one of the social media channels, I would like to discuss a job opportunity with you.. Please let me know if you are open for a change.

Reproduction

cd nucleon
cargo build

Remove Cargo.lock file and try again.

This is just an idea related to functionality that is provided by the connectable project:

It would be really great if you could dynamically create new port bindings (for example using redis) to support dynamic environments without a process restart. This way you could use nucleon as a local service proxy/loadbalancer. In addition to that a DNS backend based on SRV records could be used dynamically find all upstream servers that provide a services under a specific local port.
