Type Alias read_fonts::tables::layout::Lookup

pub type Lookup<'a, T> = TableRef<'a, LookupMarker<T>>;

Lookup Table

Aliased Type

struct Lookup<'a, T> { /* private fields */ }

Implementations

impl<'a, T> Lookup<'a, T>

pub fn lookup_type(&self) -> u16

Different enumerations for GSUB and GPOS

pub fn lookup_flag(&self) -> LookupFlag

Lookup qualifiers

pub fn sub_table_count(&self) -> u16

Number of subtables for this lookup

pub fn subtable_offsets(&self) -> &'a [BigEndian<Offset16>]

Array of offsets to lookup subtables, from beginning of Lookup table

pub fn subtables(&self) -> ArrayOfOffsets<'a, T, Offset16>

where T: FontRead<'a>,

A dynamically resolving wrapper for subtable_offsets.

pub fn mark_filtering_set(&self) -> u16

Index (base 0) into GDEF mark glyph sets structure. This field is only present if the USE_MARK_FILTERING_SET lookup flag is set.

impl<'a, T: FontRead<'a>> Lookup<'a, T>

pub fn get_subtable(&self, offset: Offset16) -> Result<T, ReadError>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, T> FontRead<'a> for Lookup<'a, T>

fn read(data: FontData<'a>) -> Result<Self, ReadError>

impl<'a, T: FontRead<'a> + SomeTable<'a> + 'a> SomeTable<'a> for Lookup<'a, T>

fn type_name(&self) -> &str

fn get_field(&self, idx: usize) -> Option<Field<'a>>

Access this table’s fields, in declaration order.
