pub fn parse_spec_set_id(s: &str) -> Result<String, Error>Expand description
Validate and normalize a spec set identifier (a spec name in the default repository).
Trims whitespace and rejects empty input, embedded whitespace, and the
version sigils ~ / ^ (which once denoted revisions and are now reserved).
Evaluation entry points use the default repository, so temporal or version
sigils on the spec set name are not accepted here.
