Struct zng_ext_font::font_features::CharVariant

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

All possible char_variant features (cv00..=cv99).

The styles depend on the font, it is recommended you create consts with named variants to use with a specific font.

Implementations

impl CharVariant

pub const fn new(v: u8) -> Self

New variant.

v == 0 || v > 99 is Auto, v >= 1 && v <= 99 maps to their variant.

pub const fn auto() -> Self

New auto.

pub const fn is_auto(self) -> bool

Is auto.

Trait Implementations

impl Clone for CharVariant

fn clone(&self) -> CharVariant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CharVariant

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

Formats the value using the given formatter.

impl FontFeatureExclusiveSetState for CharVariant

fn names() -> &'static [FontFeatureName]

All the names of features, must have more then one name.

fn variant(self) -> Option<u32>

None if Auto or Some(NonZeroUsize) if is a feature.

fn from_variant(v: u32) -> Self

New from feature variant.

fn auto() -> Self

New Auto.

impl From<u8> for CharVariant

fn from(v: u8) -> Self

v == 0 || v > 99 is Auto, v >= 1 && v <= 99 maps to their variant.

impl Hash for CharVariant

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 IntoVar<CharVariant> for u8

fn into_var(self) -> Self::Var

v == 0 || v > 99 is Auto, v >= 1 && v <= 99 maps to their variant.

type Var = LocalVar<CharVariant>

Variable type that will wrap the T value.

fn into_boxed_var(self) -> Box<dyn VarBoxed<T>>

where Self: Sized,

Converts into BoxedVar<T>.

impl PartialEq for CharVariant

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