Struct Gvar 

pub struct Gvar {
    pub axis_count: u16,
    pub shared_tuples: OffsetMarker<SharedTuples, WIDTH_32>,
    pub glyph_variation_data_offsets: Vec<GlyphVariationData>,
}

The ‘gvar’ header

Fields

axis_count: u16

The number of variation axes for this font. This must be the same number as axisCount in the ‘fvar’ table.

shared_tuples: OffsetMarker<SharedTuples, WIDTH_32>

Offset from the start of this table to the shared tuple records.

glyph_variation_data_offsets: Vec<GlyphVariationData>

Offsets from the start of the GlyphVariationData array to each GlyphVariationData table.

Implementations

impl Gvar

pub fn new( variations: Vec<GlyphVariations>, axis_count: u16, ) -> Result<Self, GvarInputError>

Construct a gvar table from a vector of per-glyph variations and the axis count.

Variations must be present for each glyph, but may be empty. For non-empty variations, the axis count must be equal to the provided axis count, as specified by the ‘fvar’ table.

Trait Implementations

impl Clone for Gvar

fn clone(&self) -> Gvar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Gvar

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

Formats the value using the given formatter.

impl Default for Gvar

fn default() -> Gvar

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Gvar

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FontWrite for Gvar

fn write_into(&self, writer: &mut TableWriter)

Write our data and information about offsets into this TableWriter.

fn table_type(&self) -> TableType

The type of this table.

impl Hash for Gvar

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 Gvar

fn cmp(&self, other: &Gvar) -> 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,

Restrict a value to a certain interval.

impl PartialEq for Gvar

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Gvar

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TopLevelTable for Gvar

const TAG: Tag

The table’s tag.

impl Validate for Gvar

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 Gvar
