Implementations

impl ChainedClassSequenceRule<'_>

fn intersects( &self, input_classes: &IntSet<u16>, backtrack_classes: &IntSet<u16>, lookahead_classes: &IntSet<u16>, ) -> bool

impl<'a> ChainedClassSequenceRule<'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 backtrack_glyph_count(&self) -> u16

Number of glyphs in the backtrack sequence

pub fn backtrack_sequence(&self) -> &'a [BigEndian<u16>]

Array of backtrack-sequence classes

pub fn input_glyph_count(&self) -> u16

Total number of glyphs in the input sequence

pub fn input_sequence(&self) -> &'a [BigEndian<u16>]

Array of input sequence classes, beginning with the second glyph position

pub fn lookahead_glyph_count(&self) -> u16

Number of glyphs in the lookahead sequence

pub fn lookahead_sequence(&self) -> &'a [BigEndian<u16>]

Array of lookahead-sequence classes

pub fn seq_lookup_count(&self) -> u16

Number of SequenceLookupRecords

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

Array of SequenceLookupRecords
