Struct Cmap14 

pub struct Cmap14<'a> { /* private fields */ }

cmap Format 14: Unicode Variation Sequences

Implementations

impl<'a> Cmap14<'a>

pub const MIN_SIZE: usize

pub fn resolve_offset<O: Offset, R: FontRead<'a, Args = ()>>( &self, offset: O, ) -> Result<R, ReadError>

Resolve the provided offset from the start of this table.

pub fn offset_data(&self) -> FontData<'a>

Return a reference to this table’s raw data.

We use this in the compile crate to resolve offsets.

pub fn shape(&self) -> &Self

👎Deprecated:

just use the base type directly

Return a reference to the table’s ‘Shape’ struct.

This is a low level implementation detail, but it can be useful in some cases where you want to know things about a table’s layout, such as the byte offsets of specific fields.

pub fn format(&self) -> u16

Subtable format. Set to 14.

pub fn length(&self) -> u32

Byte length of this subtable (including this header)

pub fn num_var_selector_records(&self) -> u32

Number of variation Selector Records

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

Array of VariationSelector records.

pub fn format_byte_range(&self) -> Range<usize>

pub fn length_byte_range(&self) -> Range<usize>

pub fn num_var_selector_records_byte_range(&self) -> Range<usize>

pub fn var_selector_byte_range(&self) -> Range<usize>

impl<'a> Cmap14<'a>

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) -> Cmap14Iter<'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) -> Cmap14Iter<'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>, )

Available on crate feature std only.
