Returns this transformer, but with a different view of the Out type.
The Out <:< Out2 implicit evidence is used to make sure the asInstanceOf cast is safe.
This is mostly useful when you know you have a transformer that yields a tuple or some kind of type constructor.

Creates a new transformer which filters the outputs from this transformer.
Creates a new transformer which filters the outputs from this transformer.
- Value parameters:
- predicate
A function which decides whether an output from this transformer should be emitted from the returned transformer.
truemeans emit,falsemeans skip.

Attach this transformer to a parser, creating a new parser that encapsulates the pair.
Values emitted from this transformer will be passed as inputs to the parser,
and the resulting output from the parser will be yielded as output by the combined parser.

Creates a new transformer which transforms the outputs of this transformer via the given function f,
emitting each individual value from the output of that function in order before continuing.

Like mergeEither, but when both sides have a common output type.
This is a less-roundabout way of doing .mergeEither(right).map(_.merge).
The same order-of-operations rules apply as with mergeEither, where this transformer "goes first" for each input.

- Inherited from:

Creates a new transformer which sends inputs to both this transformer and the right transformer.
Whenever either this or right emit a value, that value will be emitted from the returned transformer,
wrapped as a Left or Right depending on which underlying transformer emitted it.
For each individual input, the resulting values emitted by this transformer will be emitted before
the resulting values emitted by the right transformer.
