Functions

decode_composite_key

Decode a composite key into multiple values.

decode_key_value

Decode a single key value, returning the value and the number of bytes consumed.

decode_row

Decode a row into non-PK column values.

encode_composite_key

Encode a composite key (multiple values concatenated).

encode_key_value

Encode a single value into an order-preserving byte sequence.

encode_row

Encode non-PK column values into a row. Format: [col_count: u16][null_bitmap][per-column: data_type(u8) + data_len(u32) + data]
