Implementations

impl GlyphStyle

const STYLE_INDEX_MASK: u16 = 255u16

const UNASSIGNED: u16 = 255u16

const NON_BASE: u16 = 256u16

const DIGIT: u16 = 512u16

pub const fn is_unassigned(self) -> bool

pub const fn is_non_base(self) -> bool

pub const fn is_digit(self) -> bool

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

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

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.
