Trait FromObjRef 

pub trait FromObjRef<T: ?Sized>: Sized {
    // Required method
    fn from_obj_ref(from: &T, data: FontData<'_>) -> Self;
}

A trait for types that can resolve themselves when provided data to resolve offsets.

It is possible that the generated object is malformed; for instance offsets may be null where it is not allowed. This can be checked by calling validate on the generated object.

This is implemented for the majority of parse types. Those that are the base for offset data ignore the provided data and use their own.

Required Methods

fn from_obj_ref(from: &T, data: FontData<'_>) -> Self

Convert from to an instance of Self, using the provided data to resolve offsets.

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.
