I might be able to use a derived codec, actually. Just need to see what rules they follow lol
I think that'll do it.
The biggest change is definitely the removal of all the coproduct codec stuff
Partially because they no longer exist
But also because they were too clunky
thankfully I don't use scodec at work but folks definitely do. You probably know that best ;)
and the migration of everything at once might be a pain
were there other issues in upgrading scodec?
I honestly don’t know how much the coproduct stuff was used but looking back now, the Discriminated/Discriminator implicit stuff was too fancy
Main issue was replacing HList with tuples
But that’s a trivial port in most cases - 0 changes needed in common cases
hmm I think I'll have an idea, or maybe a contribution, for the derived codecs
but the derived codec gives me 8 bits
not sure if this is intentional...
yeah
what's scala's limit? hah
we could be smarter there but generally folks like byte alignment
okay found a test case for my thing
mappedEnum(uint8, Color.Red -> 10, Color.Green -> 20, Color.Blue -> 30)
given Codec[Arrows] = mappedEnum(
uint4,
Arrows.Up -> 0,
Arrows.UpRight -> 1,
Arrows.Right -> 2,
Arrows.DownRight -> 3,
Arrows.Down -> 4,
Arrows.DownLeft -> 5,
Arrows.Left -> 6,
Arrows.UpLeft -> 7,
Arrows.Neither -> 8
)
There are some downsides there where you could forget to map a case but I think the simplicity outweighs the exhaustiveness
and the shiny new scaladoc
Oh ha, no, I think scala3doc is still disabled in sbt-spiewak? Or if not, then it should be published
hello do you have any examples on how should I build a StreamEncoder from scodec-stream? I have a large binary file which I want to encode/decode that contains a huge list of elements, so I would like to be able to stream encode-decode those elements, but I cannot get a hold of how should I approach it. I do have codecs defined for the items in the file which compose a product codec that represent the whole file. Sorry if this is trivial.
Generally, use the constructors on the
StreamEncoder companion object - e.g., StreamEncoder.many(myCodec).toPipe[IO]
That's what I first tried, using the example provided in scala-stream for the StreamDecoder. But, it just tells me that the symbol many cannot be resolved and as I went inside to see what StreamEncoder contained, indeed the companion object had only the apply and instance methods. Maybe I imported the wrong thing? though I added to my build file the latest dependency from the releases page.
