Struct ImplEntry

pub struct ImplEntry<DynTrait: ?Sized> {
    pub cast_box: fn(Box<dyn Any>) -> Result<Box<DynTrait>, Box<dyn Any>>,
    pub cast_mut: fn(&mut dyn Any) -> Option<&mut DynTrait>,
    pub cast_ref: fn(&dyn Any) -> Option<&DynTrait>,
    pub tid: TypeId,
    pub from_name: &'static str,
    pub into_name: &'static str,
}
