Implementations

impl<'a> ChainedSequenceContextFormat3<'a>

pub fn format(&self) -> u16

Format identifier: format = 3

pub fn backtrack_glyph_count(&self) -> u16

Number of glyphs in the backtrack sequence

pub fn backtrack_coverage_offsets(&self) -> &'a [BigEndian<Offset16>]

Array of offsets to coverage tables for the backtrack sequence

pub fn backtrack_coverages( &self, ) -> ArrayOfOffsets<'a, CoverageTable<'a>, Offset16>

A dynamically resolving wrapper for backtrack_coverage_offsets.

pub fn input_glyph_count(&self) -> u16

Number of glyphs in the input sequence

pub fn input_coverage_offsets(&self) -> &'a [BigEndian<Offset16>]

Array of offsets to coverage tables for the input sequence

pub fn input_coverages(&self) -> ArrayOfOffsets<'a, CoverageTable<'a>, Offset16>

A dynamically resolving wrapper for input_coverage_offsets.

pub fn lookahead_glyph_count(&self) -> u16

Number of glyphs in the lookahead sequence

pub fn lookahead_coverage_offsets(&self) -> &'a [BigEndian<Offset16>]

Array of offsets to coverage tables for the lookahead sequence

pub fn lookahead_coverages( &self, ) -> ArrayOfOffsets<'a, CoverageTable<'a>, Offset16>

A dynamically resolving wrapper for lookahead_coverage_offsets.

pub fn seq_lookup_count(&self) -> u16

Number of SequenceLookupRecords

pub fn seq_lookup_records(&self) -> &'a [SequenceLookupRecord]

Array of SequenceLookupRecords

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> FontRead<'a> for ChainedSequenceContextFormat3<'a>

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

Read an instance of Self from the provided data, performing validation.

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.
