Coverage Format 1

Fields

data: FontData<'a>

Implementations

impl<'a> CoverageFormat1<'a>

pub const MIN_SIZE: usize

pub fn resolve_offset<O: Offset, R: FontRead<'a>>( &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 coverage_format(&self) -> u16

Format identifier — format = 1

pub fn glyph_count(&self) -> u16

Number of glyphs in the glyph array

pub fn glyph_array(&self) -> &'a [BigEndian<GlyphId16>]

Array of glyph IDs — in numerical order

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

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

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

impl CoverageFormat1<'_>

pub fn get(&self, gid: impl Into<GlyphId>) -> Option<u16>

If this glyph is in the coverage table, returns its index

fn intersects(&self, glyphs: &IntSet<GlyphId>) -> bool

Returns if this table contains at least one glyph in the ‘glyphs’ set.

fn intersect_set(&self, glyphs: &IntSet<GlyphId>) -> IntSet<GlyphId>

Returns the intersection of this table and input ‘glyphs’ set.

pub fn population(&self) -> usize

Return the number of glyphs in this table

pub fn cost(&self) -> u32

Return the cost of looking up a glyph in this table

Trait Implementations

impl<'a> Clone for CoverageFormat1<'a>

fn clone(&self) -> CoverageFormat1<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> FontRead<'a> for CoverageFormat1<'a>

fn read(data: FontData<'a>) -> Result<Self, ReadError>

impl Format<u16> for CoverageFormat1<'_>

const FORMAT: u16 = 1

The format value for this table.

impl<'a> MinByteRange<'a> for CoverageFormat1<'a>

fn min_byte_range(&self) -> Range<usize>
