Trait DynCastConfigTargetTest 

pub trait DynCastConfigTargetTest<C>
where
    C: ?Sized,
{ }

Used by macros to determine if a type can be coerced to a “config” type’s target trait.

If a config type implements DynCastConfigTargetTest<T> for a type T then that type can be coerced to the trait defined by <C as DynCastConfig>::Target.

This is used by the impl_dyn_cast macro to determine if it should generate code that coerces a type to the target trait or to the source trait.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
