}

Chained Sequence Context Format 3

Fields

data: FontData<'a>

Implementations

impl<'a> ChainedSequenceContextFormat3<'a>

pub const MIN_SIZE: usize

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) -> &Self

👎Deprecated: just use the base type directly

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.

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>

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>]
