pub struct LookupSubtables<'a> { /* private fields */ }

Expand description

A list of lookup subtables.

Implementations

source

impl<'a> LookupSubtables<'a>

source

pub fn len(&self) -> u16

Returns a number of items in the LookupSubtables.

source

pub fn get<T: LookupSubtable<'a>>(&self, index: u16) -> Option<T>

Parses a subtable at index.

Accepts either PositioningSubtable or SubstitutionSubtable.

Technically, we can enforce it at compile time, but it makes code too convoluted.

source

pub fn into_iter<T: LookupSubtable<'a>>(self) -> LookupSubtablesIter<'a, T>ⓘNotable traits for LookupSubtablesIter<'a, T>`impl<'a, T: LookupSubtable<'a>> Iterator for LookupSubtablesIter<'a, T> type Item = T;`

Creates an iterator over subtables.

We cannot use IntoIterator here, because we have to use user-provided base type.
