Thanks! Just for my curiosity: what do you use this library in?

[tomprogrammer]

I'm using the ascii crate in my rethinkdb database client library. In the initial handshake a parameter is restricted to contain only Ascii. Currently my API enforces that with this Ascii type.

I'm not sure if I keep it or check the Ascii-compliance in my function and accepting &str. That would move the checking and error handling from the caller to my library.

Your RFC mainly was about mixed-encoding strings so my library applies to the corner case where full Ascii strings appear. For that use-case you split std::Ascii into an external crate I guess.

[SimonSapin]

Alright. If you’re interested in maintaining the ascii crate I’m happy to give you push and publish access.

[tomprogrammer]

I can maintain the ascii-crate. I think it's very useful for strictly ascii compliant string handling.

Alright! You are now a "collaborator" in this repository and an "owner" on crates.io.

Thanks!
