Struct LookupSubtables

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

A list of lookup subtables.

Implementations

impl<'a> LookupSubtables<'a>

pub fn len(&self) -> u16

Returns a number of items in the LookupSubtables.

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.

pub fn into_iter<T: LookupSubtable<'a>>(self) -> LookupSubtablesIter<'a, T>

Creates an iterator over subtables.

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

Trait Implementations

impl<'a> Clone for LookupSubtables<'a>

fn clone(&self) -> LookupSubtables<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LookupSubtables<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
