* Add `Crc32cValue#zero()` * `Crc32cValue.zero().concat(v) == v` * Update WriteCtx to use `Crc32cValue.zero()` as it's base values rather than `null` * Update Hasher.nullSafeConcat to account for the use of `zero` * if Hasher.noop() always return null * if Hasher.enabled() only return null if left side is null * Add nullability annotation to Crc32cValue.nullSafeConcat
… as it's base values rather than `null`'
…initial crc32c value The desired default will be `Crc32cValue.zero()`, but not all tests or uploads are ready to handle this. Stick with the existing null as default, and provide the overload to selectively opt into things incrementally.
