Struct write_fonts::tables::layout::Lookup

pub struct Lookup<T> {
    pub lookup_flag: LookupFlag,
    pub subtables: Vec<OffsetMarker<T>>,
    pub mark_filtering_set: u16,
}

Lookup Table

Fields

lookup_flag: LookupFlag

Lookup qualifiers

subtables: Vec<OffsetMarker<T>>

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

mark_filtering_set: 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.
