Trait otter_nodejs_tests::cast_trait_object::DynCastExtAdvHelper

pub trait DynCastExtAdvHelper<F, T> where
    F: ?Sized,
    T: ?Sized, {
    type Target;
    type Source;

    fn _dyn_cast(self) -> Result<Self::Target, Self::Source>;
}

Used to implement DynCastExt.

Required Associated Types

type Target

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

type Source

The original trait object that is returned if the cast failed.

Required Methods

fn _dyn_cast(self) -> Result<Self::Target, Self::Source>

This method is used to cast from one trait object type to another.
