Struct write_fonts::tables::gvar::GlyphVariationDataHeader

pub struct GlyphVariationDataHeader {
    pub tuple_variation_count: TupleVariationCount,
    pub tuple_variation_headers: Vec<TupleVariationHeader>,
}

The GlyphVariationData table

Fields

tuple_variation_count: TupleVariationCount

A packed field. The high 4 bits are flags, and the low 12 bits are the number of tuple variation tables for this glyph. The number of tuple variation tables can be any number between 1 and 4095.

tuple_variation_headers: Vec<TupleVariationHeader>

Array of tuple variation headers.

Trait Implementations

impl Clone for GlyphVariationDataHeader

fn clone(&self) -> GlyphVariationDataHeader

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GlyphVariationDataHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for GlyphVariationDataHeader

fn default() -> GlyphVariationDataHeader

Returns the “default value” for a type.

impl Hash for GlyphVariationDataHeader

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for GlyphVariationDataHeader

fn cmp(&self, other: &GlyphVariationDataHeader) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for GlyphVariationDataHeader

fn eq(&self, other: &GlyphVariationDataHeader) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for GlyphVariationDataHeader

fn partial_cmp(&self, other: &GlyphVariationDataHeader) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Validate for GlyphVariationDataHeader

fn validate_impl(&self, ctx: &mut ValidationCtx)

Validate this table.

fn validate(&self) -> Result<(), ValidationReport>

Ensure that this table is well-formed, reporting any errors.

impl Eq for GlyphVariationDataHeader
