Return the case-insensitive digest of a string
std::size_t ci_digest(core::string_view s) noexcept;
The hash function is non-cryptographic and not hardened against algorithmic complexity attacks. Returned digests are suitable for usage in unordered containers. The function is defined only for strings containing low-ASCII characters.
