Module encoding 

Order-preserving key encoding and row encoding for non-PK column storage.

Enums

RawColumn

Functions

decode_column_raw

decode_column_with_offset

Like decode_column_raw but also returns the byte offset (usize::MAX if NULL).

decode_columns

decode_columns_into

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_pk_integer

decode_pk_into

decode_row

decode_row_into

encode_composite_key

Encode a composite key (multiple values concatenated).

encode_composite_key_into

encode_key_value

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

encode_row

Encode non-PK columns. Format: [col_count:u16][null_bitmap][type(u8)+len(u32)+data per col]

encode_row_into

patch_at_offset

Patch at a known byte offset. Ok(false) if size mismatch or NULL offset.

patch_column_in_place

Patch column in-place if value size unchanged. Ok(false) = size mismatch, use patch_row_column.

patch_row_column

Patch a single column in encoded row, writing result into out. Copies others unchanged.

row_non_pk_count

Returns the number of non-PK columns stored in a row value blob.
