Aliased Type

struct PairPosFormat2<'a> { /* private fields */ }

Implementations

impl<'a> PairPosFormat2<'a>

pub fn pos_format(&self) -> u16

Format identifier: format = 2

pub fn coverage_offset(&self) -> Offset16

Offset to Coverage table, from beginning of PairPos subtable.

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

Attempt to resolve coverage_offset.

pub fn value_format1(&self) -> ValueFormat

ValueRecord definition — for the first glyph of the pair (may be zero).

pub fn value_format2(&self) -> ValueFormat

ValueRecord definition — for the second glyph of the pair (may be zero).

pub fn class_def1_offset(&self) -> Offset16

Offset to ClassDef table, from beginning of PairPos subtable — for the first glyph of the pair.

pub fn class_def1(&self) -> Result<ClassDef<'a>, ReadError>

Attempt to resolve class_def1_offset.

pub fn class_def2_offset(&self) -> Offset16

Offset to ClassDef table, from beginning of PairPos subtable — for the second glyph of the pair.

pub fn class_def2(&self) -> Result<ClassDef<'a>, ReadError>

Attempt to resolve class_def2_offset.

pub fn class1_count(&self) -> u16

Number of classes in classDef1 table — includes Class 0.

pub fn class2_count(&self) -> u16

Number of classes in classDef2 table — includes Class 0.

pub fn class1_records(&self) -> ComputedArray<'a, Class1Record<'a>>

Array of Class1 records, ordered by classes in classDef1.

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 PairPosFormat2<'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.
