Type array tags CBOR

[Ottunger]

When we know that resulting Buffer (or Uint8Array in case of cbor-web) is to be used as part of a larger CBOR payload, it should be encoded using tag 24.

Is there any way to pass to encodeOne an overwrite for the tag to apply on typed array, say bufferTagType much like there already exists dateType? This would be used on the top-level encode operation.

We could solve our issue using genTypes, specifically:

const EmbeddedCBORGenTypes = {
    Uint8Array: (gen: Encoder, obj: Uint8Array) => {
        if(!gen._pushTag(0b00011000)) {
            return false;
        }
        return CBOR.Encoder._pushBuffer(gen, Buffer.from(obj))
    }
};

It's not perfect but it does the job. Is it worth searching for an alternative?

You could wrap your Buffer in a Tag, like so:

const buf = cbor.encode(...)
const t = new cbor.Tagged(24, buf)
return cbor.encode(t)
