AsyncFileChannelConsumer

Given a source Observable, convert it into a Task by piggybacking on createSubscriber.

Given a contravariant mapping function, transform the source consumer by transforming the input.

Given a mapping function, when consuming a stream, applies the mapping function to the final result, thus modifying the output of the source consumer.

Note that for applying the mapping function an asynchronous boundary is forced, otherwise it could trigger a stack overflow exception. For more efficient mapping of the result, it's probably better to map the resulting Task on Observable.consumeWith.

Given a mapping function, when consuming a stream, applies the mapping function to the final result, thus modifying the output of the source consumer.

The mapping function returns results using a generic F[_] data type that must implement the cats.effect.Effect type class. Examples of such classes are cats.effect.IO and monix.eval.Task, thus being able to do asynchronous processing.

See mapTask for the version that's specialized on Task.

Given a mapping function, when consuming a stream, applies the mapping function to the final result, thus modifying the output of the source consumer.

The mapping function returns a Task that can be used to process results asynchronously.

Note that for applying the mapping function an asynchronous boundary is forced, otherwise it could trigger a stack overflow exception. For more efficient mapping of the result, it's probably better to map the resulting Task on Observable.consumeWith.

See mapEval for the version that can work with any data type that implements cats.effect.Effect.

Given a function that transforms the input stream, uses it to transform the source consumer into one that accepts events of the type specified by the transformation function.
