Enum zng_ext_font::font_features::NumVariant

#[repr(u8)]
pub enum NumVariant {
    Auto = 0,
    Lining = 1,
    OldStyle = 2,
}

Font numeric variant features.

Variants

Auto = 0

Uses the default numeric glyphs, in most fonts this is the same as Lining, some fonts use the OldStyle.

Lining = 1

Uses numeric glyphs that rest on the baseline.

This corresponds to OpenType lnum feature.

OldStyle = 2

Uses old-style numeric glyphs, where some numbers, like 3, 4, 7, 9 have descenders.

This corresponds to OpenType onum feature.

Trait Implementations

impl Clone for NumVariant

fn clone(&self) -> NumVariant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NumVariant

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

Formats the value using the given formatter.

impl Default for NumVariant

fn default() -> Self

NumVariant::Auto

impl FontFeatureExclusiveSetState for NumVariant

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 NumVariant

fn from(number: u8) -> Self

Converts to this type from the input type.

impl FromPrimitive for NumVariant

type Primitive = u8

fn from_primitive(number: Self::Primitive) -> Self

impl Hash for NumVariant

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 PartialEq for NumVariant

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