Feature to disable SSL

[Proximyst]

I'm writing a service which is designed to be ran in Docker where SSL really only adds unnecessary overhead and is as such not used. I'd love for a feature gate to disable SSL altogether in this crate. I personally do not care if SSL is enabled by default, as long as it is possible to remove SSL.

Thank you! :)

Depends on the database. For instance, you can add ?sslmode=disable for postgres.

I'm aware how to disable the SSL from the connection, I'm saying I'd prefer if I didn't have a dependency on the openssl crate at all. This is completely fine if you smack a "priority: low" or something label on, though, as it's not exactly a problem per se.

I have problems with the openssl crate as well on NixOS. I can either get fast linking with lld or working openssl linking, but not both.

Edit: I just noticed things works fine for me with https://github.com/launchbadge/sqlx/issues/473#issuecomment-655517309, thank you for that very helpful pointer.

I think this is possible in rust 1.60 https://blog.rust-lang.org/2022/04/07/Rust-1.60.0.html
