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

Lookup Table

Implementations

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

pub fn lookup_type(&self) -> u16

Different enumerations for GSUB and GPOS

pub fn lookup_flag(&self) -> u16

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) -> impl Iterator<Item = Result<T, ReadError>> + 'awhere
    T: FontRead<'a>,

Attempt to resolve 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.
