[−][src]Trait cast_trait_object::DynCastConfigTargetTest
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.
