class MyObject {

static read(cursor: Cursor): Result<MyObject, Error> {
return Result.unthrowSync(() => {
const x = cursor.tryReadUint8().throw()
const y = cursor.tryReadUint16().throw()

}
}
const bytes = new Uint8Array([1, 2, 3])
const myobject = Readable.tryReadFromBytes(MyObject, bytes).unwrap() // MyObject(1, 515)
This is a binary data type that just holds bytes, it can be used when a binary data type is required
const bytes = new Uint8Array([1, 2, 3])
const opaque = Readable.tryReadFromBytes(SafeOpaque, bytes).unwrap() // Opaque(Uint8Array([1, 2, 3]))
const myobject = opaque.tryInto(MyObject).unwrap() // MyObject(1, 515)
const myobject = new MyObject(1, 515)
const opaque = Opaque.tryFrom(myobject).unwrap() // Opaque(Uint8Array([1, 2, 3]))
const bytes = Writable.tryWriteToBytes(opaque).unwrap() // Uint8Array([1, 2, 3])
