Struct GlyphMap

pub struct GlyphMap { /* private fields */ }

A glyph map for mapping from raw glyph identifiers to numeral GlyphId16s.

This is used to map from names or CIDS encountered in a FEA file to the actual GlyphId16s that will be used in the final font.

Currently, the only way to construct this type is by calling collect() on an iterator of cids or names.

Implementations

impl GlyphMap

pub fn len(&self) -> usize

The total number of glyphs

pub fn is_empty(&self) -> bool

Returns true if this map contains no glyphs

pub fn reverse_map(&self) -> BTreeMap<GlyphId16, GlyphIdent>

Generates a reverse map of ids -> raw identifers (names or CIDs)

pub fn iter(&self) -> impl Iterator<Item = GlyphIdent> + '_

Iterate the idents in this map, in GID order.

This is really only intended to be used to create new glyphmaps for testing.

pub fn contains<Q: ?Sized + AsGlyphIdent>(&self, key: &Q) -> bool

Return true if the map contains the provided GlyphIdent.

pub fn get<Q: ?Sized + AsGlyphIdent>(&self, key: &Q) -> Option<GlyphId16>

Return the GlyphId16 for the provided GlyphIdent

pub fn make_post_table(&self) -> Post

Generate a post table from this glyph map

Trait Implementations

impl Clone for GlyphMap

fn clone(&self) -> GlyphMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GlyphMap

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

Formats the value using the given formatter.

impl Default for GlyphMap

fn default() -> GlyphMap

Returns the “default value” for a type.

impl FromIterator<GlyphIdent> for GlyphMap

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

Creates a value from an iterator.

impl FromIterator<GlyphName> for GlyphMap

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

Creates a value from an iterator.

impl FromIterator<u16> for GlyphMap

fn from_iter<T: IntoIterator<Item = u16>>(iter: T) -> Self

Creates a value from an iterator.

impl PartialEq for GlyphMap

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

Tests for self and other values to be equal, and is used by ==.

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

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