# Struct TupleIndex

    pub struct TupleIndex(/* private fields */);

## Implementations§

§

### impl TupleIndex

#### pub const EMBEDDED_PEAK_TUPLE: u16 = 32_768u16

Flag indicating that this tuple variation header includes an embedded peak tuple record, immediately after the tupleIndex field.

If set, the low 12 bits of the tupleIndex value are ignored.

Note that this must always be set within the ‘cvar’ table.

#### pub const INTERMEDIATE_REGION: u16 = 16_384u16

Flag indicating that this tuple variation table applies to an intermediate region within the variation space.

If set, the header includes the two intermediate-region, start and end tuple records, immediately after the peak tuple record (if present).

#### pub const PRIVATE_POINT_NUMBERS: u16 = 8_192u16

Flag indicating that the serialized data for this tuple variation table includes packed “point” number data.

If set, this tuple variation table uses that number data; if clear, this tuple variation table uses shared number data found at the start of the serialized data for this glyph variation data or ‘cvar’ table.

#### pub const TUPLE_INDEX_MASK: u16 = 4_095u16

Mask for the low 12 bits to give the shared tuple records index.

#### pub fn bits(self) -> u16

#### pub fn from_bits(bits: u16) -> TupleIndex

#### pub fn embedded_peak_tuple(self) -> bool

`true` if the header includes an embedded peak tuple.

#### pub fn intermediate_region(self) -> bool

`true` if the header includes the two intermediate region tuple records.

#### pub fn private_point_numbers(self) -> bool

`true` if the data for this table includes packed point number data.

#### pub fn tuple_records_index(self) -> Option<u16>
