#[repr(transparent)]
pub struct GlyphStyle(pub(super) u16);

Defines the script and style associated with a single glyph.

0: u16

Implementations

impl GlyphStyle

const STYLE_INDEX_MASK: u16 = 0xFF

const UNASSIGNED: u16 = Self::STYLE_INDEX_MASK

const NON_BASE: u16 = 0x100

const DIGIT: u16 = 0x200

const FROM_GSUB_OUTPUT: u16 = 0x8000

pub const fn from_raw_parts( style_index: u16, is_non_base: bool, is_digit: bool, ) -> Self

Constructs a new glyph style from the given style index and properties.

pub const fn is_unassigned(self) -> bool

Returns true if this glyph doesn’t have an assigned style.

pub const fn is_non_base(self) -> bool

Returns true if this glyph is a non-base (usually a mark).

pub const fn is_digit(self) -> bool

Returns true if this glyph is a digit.

pub fn style_class(self) -> Option<&'static StyleClass>

Returns the associated style class for this glyph.

pub const fn style_index(self) -> Option<u16>

Returns the index of the style class for this class.

fn maybe_assign(&mut self, other: Self)

pub(super) fn set_from_gsub_output(&mut self)

pub(super) fn clear_from_gsub(&mut self)

pub(super) fn maybe_assign_gsub_output_style( &mut self, style: &StyleClass, ) -> bool

Assign a style if we’ve been marked as GSUB output and the we don’t currently have an assigned style.

This also clears the GSUB output bit.

Returns true if this style was applied.

Trait Implementations

impl Clone for GlyphStyle

fn clone(&self) -> GlyphStyle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GlyphStyle

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

Formats the value using the given formatter.

impl Default for GlyphStyle

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for GlyphStyle

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