    Implementation of the reactivestreams protocol for fs2

    Deprecated

    The next major version of fs2 will drop these converters. Rather, users will be encouraged to use the new fs2.interop.flow package, which provides support for the java.util.concurrent.Flow types; that superseded the reactive-streams library. In case you need to interop with a library that only provides reactive-streams types, you may use org.reactivestreams.FlowAdapters

    Example:

    1. scala> import fs2._
scala> import fs2.interop.reactivestreams._
scala> import cats.effect.{IO, Resource}, cats.effect.unsafe.implicits.global
scala>
scala> val upstream: Stream[IO, Int] = Stream(1, 2, 3).covary[IO]
scala> val publisher: Resource[IO, StreamUnicastPublisher[IO, Int]] = upstream.toUnicastPublisher
scala> val downstream: Stream[IO, Int] = Stream.resource(publisher).flatMap(_.toStreamBuffered[IO](bufferSize = 16))
scala>
scala> downstream.compile.toVector.unsafeRunSync()
res0: Vector[Int] = Vector(1, 2, 3)

    bufferSize

    setup the number of elements asked each time from the org.reactivestreams.Publisher. A high number can be useful if the publisher is triggering from IO, like requesting elements from a database. The publisher can use this bufferSize to query elements in batch. A high number will also lead to more elements in memory.

    (Since version 3.1.4) Use toStreamBuffered method instead. Use a buffer size of 1 to keep the same behavior.
