Struct UvsSubtable 

pub struct UvsSubtable<'a> {
    data: FontData<'a>,
    selectors: &'a [VariationSelector],
    format: u16,
}

A Unicode variation sequences subtable: format 14, or format 15, whose non-default mappings carry 24-bit glyph IDs.

Fields

data: FontData<'a>

selectors: &'a [VariationSelector]

format: u16

Implementations

impl<'a> UvsSubtable<'a>

pub fn format(&self) -> u16

The subtable format: 14, or 15 for 24-bit glyph IDs.

pub fn var_selector(&self) -> &'a [VariationSelector]

The variation selector records, sorted by selector.

pub fn map_variant( &self, codepoint: impl Into<u32>, selector: impl Into<u32>, ) -> Option<MapVariant>

Maps a codepoint and variation selector to a nominal glyph identifier.

pub fn iter(&self) -> UvsSubtableIter<'a>

Returns an iterator over all (codepoint, selector, mapping variant) triples in the subtable.

Malicious and malformed fonts can produce a large number of invalid triples. Use Self::iter_with_limits to generate a pruned sequence that is limited to reasonable values.

pub fn iter_with_limits(&self, limits: CmapIterLimits) -> UvsSubtableIter<'a>

Returns an iterator over all (codepoint, selector, mapping variant) triples in the subtable within the given limits.

pub fn closure_glyphs( &self, unicodes: &IntSet<u32>, glyph_set: &mut IntSet<GlyphId>, )

fn non_default_uvs( &self, record: &VariationSelector, ) -> Option<NonDefaultUvsIter<'a>>

The non-default mappings of a selector record, if present and readable.

Trait Implementations

impl<'a> Clone for UvsSubtable<'a>

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

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

Performs copy-assignment from source.

impl<'a> From<Cmap14<'a>> for UvsSubtable<'a>

impl<'a> From<Cmap15<'a>> for UvsSubtable<'a>

fn from(table: Cmap15<'a>) -> Self

Converts to this type from the input type.
