Module compare 

Byte-level comparison and hashing for MessagePack field values.

Operates on raw byte ranges returned by extract_field. Used for join key matching, GROUP BY key deduplication, ORDER BY, and DISTINCT.

Functions

compare_field_bytes

Compare two MessagePack values by their decoded content.

compare_field_i64

Compare two numeric MessagePack values as i64. Useful when the caller knows both values are integers.

field_bytes_eq

Check if two MessagePack values are byte-identical. For canonical-encoded documents, byte equality implies semantic equality.

hash_field_bytes

Hash the raw bytes of a MessagePack value at range within buf. Uses a fast non-cryptographic hash suitable for hash joins and GROUP BY.

hash_field_bytes_with

Hash the raw bytes using a provided RandomState for consistent hashing within a single query (all docs hashed with the same seed).

is_field_null

Check if a field value is null without extracting it.
