TupleVariationHeader

Fields

variation_data_size: u16

The size in bytes of the serialized data for this tuple variation table.

tuple_index: TupleIndex

A packed field. The high 4 bits are flags (see below). The low 12 bits are an index into a shared tuple records array.

peak_tuple: Vec<F2Dot14>

Peak tuple record for this tuple variation table — optional, determined by flags in the tupleIndex value. Note that this must always be included in the ‘cvar’ table.

intermediate_start_tuple: Vec<F2Dot14>

Intermediate start tuple record for this tuple variation table — optional, determined by flags in the tupleIndex value.

intermediate_end_tuple: Vec<F2Dot14>

Intermediate end tuple record for this tuple variation table — optional, determined by flags in the tupleIndex value.
