Trait LookupSubtable 

pub trait LookupSubtable {
    const TYPE: LookupType;
}

A utility trait for writing lookup tables.

This allows us to attach the numerical lookup type to the appropriate concrete types, so that we can write it as needed without passing it around.

Required Associated Constants

const TYPE: LookupType

The lookup type of this layout subtable.

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.
