Struct SfntUnicodeCharmap 

pub(crate) struct SfntUnicodeCharmap<'a> {
    cmap: UnicodeSubtables<'a>,
    dmap: UnicodeSubtables<'a>,
}

The selected cmap subtables and the metadata needed to use them.

Fields

cmap: UnicodeSubtables<'a>

dmap: UnicodeSubtables<'a>

Implementations

impl<'a> SfntUnicodeCharmap<'a>

pub(crate) fn read(font: &impl TableProvider<'a>) -> Self

pub(crate) fn map(&self, codepoint: u32) -> Option<GlyphId>

fn map_batched<'o>( &self, codepoints: impl Iterator<Item = (u32, &'o mut GlyphId)>, ) -> usize

Writes the mapping of each codepoint to its slot and returns the number of initial consecutive nonzero mappings.

DMAP overrides cmap codepoint by codepoint, so only a font without one runs through the cached lookups of a single subtable.

pub(crate) fn map_variant( &self, codepoint: u32, selector: u32, ) -> Option<GlyphId>

fn iter( &self, limits: CmapIterLimits, ) -> impl Iterator<Item = (u32, GlyphId)> + '_

fn variant_mappings( &self, limits: CmapIterLimits, ) -> impl Iterator<Item = (u32, u32, MapVariant)> + '_

Trait Implementations

impl<'a> Clone for SfntUnicodeCharmap<'a>

fn clone(&self) -> SfntUnicodeCharmap<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Default for SfntUnicodeCharmap<'a>

fn default() -> SfntUnicodeCharmap<'a>

Returns the “default value” for a type.

impl<'yoke> Yokeable<'yoke> for SfntUnicodeCharmap<'static>

type Output = SfntUnicodeCharmap<'yoke>

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&'yoke self) -> &'yoke Self::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> Self::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make(from: Self::Output) -> Self

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'yoke mut self, f: F)

where F: 'static + for<'_yoke> FnOnce(&'_yoke mut Self::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.
