Struct fea_rs::GlyphMap

pub struct GlyphMap { /* private fields */ }

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

This is used to map from names or CIDS encountered in a FEA file to the actual GlyphIds 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<GlyphId, 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<GlyphId>

Return the GlyphId for the provided GlyphIdent

pub fn make_post_table(&self) -> Post

Generate a post table from this glyph map
