Crate names unable to have digits

[b-ncMN]

Describe the problem you are trying to solve
Today, we had a project for uni, we could use any programming language to solve the problem and I wanted to use Rust as the language to solve the problem, unfortunately, in the specifications, we were told we needed the compiled binary that needed to be named "101Pong". So I tried creating a crate with that name, and cargo didn't let me do it.

Describe the solution you'd like
I'd like to see an option that can let one force the name of the crate even tho it is not authorized to have a crate with digits in front of the name, (I will not upload that crate to anywhere except a private GitHub repository), this would be great so that person doesn't have to use an external tool (like make/Makefile) to invoke the compilation process and then rename the binary from an authorized name to a non-authorized name

Notes

You can change the name of the binary in Cargo.toml by setting the name field:

[[bin]]
name = "101Pong"

The associated filename would default to src/bin/101Pong.rs or you can explicitly set the filename like path = "src/main.rs".

I think it is unlikely we would change it to allow package names to start with numbers due to the problems that could cause, but I think it would be good to add this tip to the cargo new error message.

You can learn more about Cargo targets and default filenames at https://doc.rust-lang.org/cargo/reference/cargo-targets.html.

Okay, thanks for the tip, I wanted to be able to name my directory and crate the same name the exercise was but I guess I won't be able to

@ehuss is this supposed to be an open issue? or is the OP request not meant to be possible at all?

@joao-conde This issue is open to track updating the error message. I have posted #9098 to close this.
