Module encode 

Binary Tuple encoder: schema + values → compact byte representation.

Layout:

[magic: u32 LE = 0x5453_444E "NDST"]   bytes 0..4
[format_version: u8 = 1]               byte 4
[schema_version: u32 LE]               bytes 5..9
[null_bitmap: ceil(N/8) bytes, bit=1 means NULL]
[fixed_fields: concatenated, zeroed when null]
[offset_table: (N_var + 1) × u32 LE]
[variable_data: concatenated variable-length bytes]

Structs

TupleEncoder

Encodes rows into Binary Tuples according to a fixed schema.

Constants

FORMAT_VERSION

Current Binary Tuple format version.

MAGIC

Magic bytes identifying a Binary Tuple: "NDST" in little-endian.
