Enum zng_ext_font::font_features::NumSpacing

#[repr(u8)]
pub enum NumSpacing {
    Auto = 0,
    Proportional = 1,
    Tabular = 2,
}

Font numeric spacing features.

Variants

Auto = 0

Uses the default numeric width, usually this is Tabular for monospace fonts and Proportional for the others.

Proportional = 1

Numeric glyphs take different space depending on the design of the glyph.

This corresponds to OpenType pnum feature.

Tabular = 2

Numeric glyphs take the same space even if the glyphs design width is different.

This corresponds to OpenType tnum feature.

Trait Implementations

impl Clone for NumSpacing

fn clone(&self) -> NumSpacing

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NumSpacing

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

Formats the value using the given formatter.

impl Default for NumSpacing

fn default() -> Self

NumSpacing::Auto

impl FontFeatureExclusiveSetState for NumSpacing

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 NumSpacing

fn from(number: u8) -> Self

Converts to this type from the input type.

impl FromPrimitive for NumSpacing

type Primitive = u8

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

impl Hash for NumSpacing

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 NumSpacing

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