GlyphPatches

Aliased Type

struct GlyphPatches<'a> { /* private fields */ }

Implementations

impl<'a> GlyphPatches<'a>

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

A constructor that requires additional arguments.

This type requires some external state in order to be parsed.

impl<'a> GlyphPatches<'a>

pub fn glyph_count(&self) -> u32

pub fn table_count(&self) -> u8

pub fn glyph_ids(&self) -> ComputedArray<'a, U16Or24>

pub fn tables(&self) -> &'a [BigEndian<Tag>]

pub fn glyph_data_offsets(&self) -> &'a [BigEndian<Offset32>]

pub fn glyph_data(&self) -> ArrayOfOffsets<'a, GlyphData<'a>, Offset32>

A dynamically resolving wrapper for glyph_data_offsets.

impl<'a> GlyphPatches<'a>

pub fn glyph_data_for_table( &'a self, table_index: usize, ) -> impl Iterator<Item = Result<(GlyphId, &'a [u8]), ReadError>>

Returns an iterator over the per glyph data for the table with the given index.

impl<'a, T> TableRef<'a, T>

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) -> &T

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.

Trait Implementations

impl<'a> FontReadWithArgs<'a> for GlyphPatches<'a>

fn read_with_args( data: FontData<'a>, args: &GlyphKeyedFlags, ) -> Result<Self, ReadError>

read an item, using the provided args.

impl ReadArgs for GlyphPatches<'_>

type Args = GlyphKeyedFlags

impl<'a, T: Clone> Clone for TableRef<'a, T>

fn clone(&self) -> TableRef<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.
