Take While

How to take bytes until a condition is met and then close resource


    import scalax.io._

    val in:Input = Resource.fromURLString("file://someFile")

    // take bytes until they one is greater than 5
    // Note: bytes is a view which means it does not open the
    // resource until the actual data is requested.
    // The following statement does not access resource
    val lessThan5 = in.bytesAsInts.takeWhile(_ &lt; 5)


    // This statement will open resource take add
    // bytes together (until a byte greater than 5)
    // and close resource.
    val sum = lessThan5.reduceLeft(_ + _)
