Aliased Type§

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

Implementations§

Source§

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

Source

pub fn lookup_type(&self) -> u16

Different enumerations for GSUB and GPOS

Source

pub fn lookup_flag(&self) -> LookupFlag

Lookup qualifiers

Source

pub fn sub_table_count(&self) -> u16

Number of subtables for this lookup

Source

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

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

Source

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

A dynamically resolving wrapper for subtable_offsets.

Source

pub fn mark_filtering_set(&self) -> Option<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.
