Implementations

impl<'a> MultipleSubstFormat1<'a>

pub fn subst_format(&self) -> u16

Format identifier: format = 1

pub fn coverage_offset(&self) -> Offset16

Offset to Coverage table, from beginning of substitution subtable

pub fn coverage(&self) -> Result<CoverageTable<'a>, ReadError>

Attempt to resolve coverage_offset.

pub fn sequence_count(&self) -> u16
