pub fn camel_tokens(word: &str) -> Vec<String>Expand description
Splits a single camelCase/PascalCase word into lowercase tokens, treating
runs of consecutive capitals as an acronym token of their own (e.g.
"HTTPServer" -> ["http", "server"]). Exact regex ported from
build_combined_schema.py: [A-Z]?[a-z0-9]+|[A-Z]+(?=[A-Z]|$).
