Struct ConcreteDynCastConfig 

pub struct ConcreteDynCastConfig<S, T>
where
    S: ?Sized,
    T: ?Sized,
{ /* private fields */ }

This is an implementation detail for the macros that implement DynCast.

Used to create a specify a “config” type when only the source and target traits are known.

This type implements DynCastConfig and there is a blanket implementation of DynCast so that if DynCast is implemented for ConcreteDynCastConfig<dyn Source, dyn Target> then DynCast is implemented for all “config” types that implement DynCastConfig<Source = dyn Source, Target = dyn Target>.

impl<S, T> DynCastConfig for ConcreteDynCastConfig<S, T>

where S: ?Sized, T: ?Sized,

type Target = T

type Source = S
