# cast<RS, RT> method

Converter<RS, RT> cast <RS, RT>()

Provides a `Converter<RS, RT>` view of this stream transformer.

The resulting transformer will check at run-time that all conversion inputs are actually instances of `S`, and it will check that all conversion output produced by this converter are acually instances of `RT`.

## Implementation

    Converter<RS, RT> cast<RS, RT>() => Converter.castFrom<S, T, RS, RT>(this);
