Chained Sequence Context Format 2

Aliased Type

struct ChainedSequenceContextFormat2<'a> { /* private fields */ }

Implementations

impl<'a> ChainedSequenceContextFormat2<'a>

pub fn format(&self) -> u16

Format identifier: format = 2

pub fn coverage_offset(&self) -> Offset16

Offset to Coverage table, from beginning of ChainedSequenceContextFormat2 table

pub fn coverage(&self) -> Result<CoverageTable<'a>, ReadError>

Attempt to resolve coverage_offset.

pub fn backtrack_class_def_offset(&self) -> Offset16

Offset to ClassDef table containing backtrack sequence context, from beginning of ChainedSequenceContextFormat2 table

pub fn backtrack_class_def(&self) -> Result<ClassDef<'a>, ReadError>

Attempt to resolve backtrack_class_def_offset.

pub fn input_class_def_offset(&self) -> Offset16

Offset to ClassDef table containing input sequence context, from beginning of ChainedSequenceContextFormat2 table

pub fn input_class_def(&self) -> Result<ClassDef<'a>, ReadError>

Attempt to resolve input_class_def_offset.

pub fn lookahead_class_def_offset(&self) -> Offset16

Offset to ClassDef table containing lookahead sequence context, from beginning of ChainedSequenceContextFormat2 table

pub fn lookahead_class_def(&self) -> Result<ClassDef<'a>, ReadError>

Attempt to resolve lookahead_class_def_offset.

pub fn chained_class_seq_rule_set_count(&self) -> u16

Number of ChainedClassSequenceRuleSet tables

pub fn chained_class_seq_rule_set_offsets( &self, ) -> &'a [BigEndian<Nullable<Offset16>>]

Array of offsets to ChainedClassSequenceRuleSet tables, from beginning of ChainedSequenceContextFormat2 table (may be NULL)

pub fn chained_class_seq_rule_sets( &self, ) -> ArrayOfNullableOffsets<'a, ChainedClassSequenceRuleSet<'a>, Offset16>

A dynamically resolving wrapper for chained_class_seq_rule_set_offsets.

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 ChainedSequenceContextFormat2<'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.
