Implementations

impl<'a> ExtensionSubtable<'a>

pub(crate) fn of_unit_type(&self) -> ExtensionSubstFormat1<'a, ()>

Return the inner table, removing the specific generics.

This lets us return a single concrete type we can call methods on.

impl<'a> ExtensionSubtable<'a>

fn dyn_inner(&self) -> &(dyn SomeTable<'a> + 'a)

Trait Implementations

impl Debug for ExtensionSubtable<'_>

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

Formats the value using the given formatter.

impl<'a> FontRead<'a> for ExtensionSubtable<'a>

fn read(bytes: FontData<'a>) -> Result<Self, ReadError>

Read an instance of Self from the provided data, performing validation.

impl<'a> SomeTable<'a> for ExtensionSubtable<'a>

fn get_field(&self, idx: usize) -> Option<Field<'a>>

Access this table’s fields, in declaration order.

fn type_name(&self) -> &str

The name of this table
