Struct zng_ext_font::font_features::FontVariations

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

A small map of font variations.

Use font_variations! to manually initialize.

Implementations

impl FontVariations

pub fn new() -> Self

New empty.

pub fn with_capacity(capacity: usize) -> Self

New empty with pre-allocated capacity.

pub fn from_pairs(pairs: &[(FontVariationName, f32)]) -> Self

New font variations from pairs of name, value.

pub fn insert(&mut self, name: FontVariationName, value: f32) -> Option<f32>

Insert the font variation, returns the previous value if the variation was already set.

pub fn remove(&mut self, name: FontVariationName) -> Option<f32>

Remove the font variation, returns the value if the variation was set.

pub fn contains(&self, name: FontVariationName) -> bool

If the variation is set.

pub fn get(&self, name: FontVariationName) -> Option<f32>

Gets a copy of the variation value if it is set.

pub fn get_mut(&mut self, name: FontVariationName) -> Option<&mut f32>

Exclusive borrow the variation value if it is set.

pub fn len(&self) -> usize

Count of font variations set.

pub fn is_empty(&self) -> bool

If not font variation is set.

pub fn finalize(&self) -> RFontVariations

Finalize variations config for use in a font.

Trait Implementations

impl Clone for FontVariations

fn clone(&self) -> FontVariations

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

Performs copy-assignment from source.

impl Debug for FontVariations

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

Formats the value using the given formatter.

impl Default for FontVariations

fn default() -> FontVariations

Returns the “default value” for a type.

fn eq(&self, other: &FontVariations) -> 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.
