Trait otter_api_tests::imports::cast_trait_object::DynCastExtHelper

pub trait DynCastExtHelper<T> where
    T: ?Sized, {
    type Target;
    type Source;
    type Config;
    pub fn _dyn_cast(self) -> Result<Self::Target, Self::Source>;
}

Used to implement DynCastExt.

Associated Types

type Target

The wanted trait object that is returned if the cast succeeded.

type Source
