fn loca(&self, is_long: impl Into<Option<bool>>) -> Result<Loca<'a>, ReadError>
fn loca(&self, is_long: impl Into<Option<bool>>) -> Result<Loca<'a>, ReadError>
is_long can be optionally provided, if known, otherwise we look it up in head.
fn glyf(&self) -> Result<TableRef<'a, GlyfMarker>, ReadError>

fn cvt(&self) -> Result<&'a [BigEndian<i16>], ReadError>
fn cvt(&self) -> Result<&'a [BigEndian<i16>], ReadError>
Returns the array of entries for the control value table which is used for TrueType hinting.

Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
