Struct write_fonts::tables::layout::CoverageTableBuilder

pub struct CoverageTableBuilder { /* private fields */ }

A builder for CoverageTable tables.

This will choose the best format based for the included glyphs.

Implementations

impl CoverageTableBuilder

pub fn from_glyphs(glyphs: Vec<GlyphId>) -> Self

Create a new builder from a vec of GlyphId.

pub fn add(&mut self, glyph: GlyphId) -> u16

Add a GlyphId to this coverage table.

Returns the coverage index of the added glyph.

If the glyph already exists, this returns its current index.

pub fn build(self) -> CoverageTable

Convert this builder into the appropriate CoverageTable variant.

Trait Implementations

impl Debug for CoverageTableBuilder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CoverageTableBuilder

fn default() -> CoverageTableBuilder

Returns the “default value” for a type.

impl FromIterator<GlyphId> for CoverageTableBuilder

fn from_iter<T: IntoIterator<Item = GlyphId>>(iter: T) -> Self

Creates a value from an iterator.

impl PartialEq<CoverageTableBuilder> for CoverageTableBuilder

fn eq(&self, other: &CoverageTableBuilder) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
