@rustlang and community, how do I obtain the only group in this example with the regex crate? Having difficulties with Captures...pic.twitter.com/JJzCfX6vbu
Is it always “Full name: A B” where A, B could expand? Just in case, mine allows a first name without last name /\w+\s\w+:\s(\w+\s?\w*)/ That’s PCRE, I believe, crate might expect slightly different syntax.
If it’s only full names you want, you could simplify this to /Full name: (\w+\s?\w*)/ or similar
maybe play with a site like http://regex101.com to practice if that could help, but if you’re comfy with regex and it’s crate specific issue idk 
I've used regex101 to practice, but it worked for me there? :c
So regex101 uses different engines (JavaScript, ruby, python etc I think) than the rust crate uses, so that could explain discrepancies. The crate author will know, but check if the crate is PCRE compliant to know if a bug happened or what
regex101 has Go's regex engine, which will be very close to Rust's regex engine. (They share a common ancestor.) Otherwise, Rust's regex crate is "roughly" a subset of what PCRE will give you. (Notable absences: lookaround and backreferences.)
