Functions

find_latest_stable

Finds the latest stable version from a list of versions.

has_default_prerelease_marker

hash_routing_key

Hashes an ordered sequence of &str routing-hop parts into an opaque "{prefix}:{digest:016x}" chain-identity key, using std::collections::hash_map::DefaultHasher.

is_existence_wildcard

Whether req is a wildcard/empty requirement ("" or "*", ignoring surrounding whitespace) rather than a concrete version constraint.

is_existence_wildcard_str

is_existence_wildcard for a raw &str, without allocating a VersionReq wrapper.

select_latest_for_existence

Index of the version an existence check should report as “latest”, ignoring req entirely.
