Charify

A simple proc macro to turn its token input into a char, similar to the built-in stringify! macro.

Examples

println!("Hell{}, w{}rld!", charify!(o), charify!(o));

Result: "Hello, world!"

println!("What{} Outrageous{}", charify!(?), charify!(!))

Result: "What? Outrageous!"

Known issues

Somehow, the proc macro causes a strange issue that reports "range end index 4 out of range for slice of length 3". I have no idea what this is referring to, and it's not a true compile error, as it compiles and runs fine. It appears that only rust-analyzer has a problem. If this is something I can fix, please let me know (open an issue on github) and I will fix it, but as it stands I think this is just a bug in rust-analyzer.
