Struct PairPosFormat3 

pub struct PairPosFormat3<'a> {
    data: TableDataRef<'a, PairPosFormat3FixedHeader>,
}

PairPosFormat3 (ISO/IEC 14496-22:2026).

Fields

data: TableDataRef<'a, PairPosFormat3FixedHeader>

Implementations

impl<'a> PairPosFormat3<'a>

pub const MIN_SIZE: usize

pub fn resolve_offset<O: Offset, R: FontRead<'a, Args = ()>>( &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 pos_format(&self) -> u16

Format identifier: format = 3

pub fn coverage_offset(&self) -> Offset32

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

Defines the types of data in valueRecord1 — for the first glyph in the pair (may be zero).

pub fn value_format2(&self) -> ValueFormat

Defines the types of data in valueRecord2 — for the second glyph in the pair (may be zero).

pub fn pair_set_count(&self) -> Uint24

Number of PairSet tables

pub fn pair_set_offsets(&self) -> &'a [BigEndian<Offset24>]

Array of offsets to PairSet tables. Offsets are from beginning of PairPos subtable, ordered by Coverage Index.

pub fn pair_sets(&self) -> ArrayOfOffsets<'a, PairSet2<'a>, Offset24>

A dynamically resolving wrapper for pair_set_offsets.

pub fn pos_format_byte_range(&self) -> Range<usize>

pub fn coverage_offset_byte_range(&self) -> Range<usize>

pub fn value_format1_byte_range(&self) -> Range<usize>

pub fn value_format2_byte_range(&self) -> Range<usize>

pub fn pair_set_count_byte_range(&self) -> Range<usize>

pub fn pair_set_offsets_byte_range(&self) -> Range<usize>

Trait Implementations

impl<'a> Clone for PairPosFormat3<'a>

fn clone(&self) -> PairPosFormat3<'a>
