Specification
Interface specification is the following Contractum code:
-- Defined by LNPBP-31 standard in `RGBContract.sty` file
import urn:ubideco:stl:6vbr9ZrtsD9aBjo5qRQ36QEZPVucqvRRjKCPqE8yPeJr#choice-little-boxer as RGBContract
import urn:ubideco:stl:9KALDYR8Nyjq4FdMW6kYoL7vdkWnqPqNuFnmE9qHpNjZ#justice-rocket-type as Std
interface RGB24
global root :: RGBContract.ContractId?
global name :: Std.Ident
global {registry} :: Record
global created :: RGBContract.Timestamp
owned registar
op Register :: registar, {registry ^ 1..0xFFFF} -> registar
!! noRoot |
invalidRoot |
incompleteRegistry
data Hostname :: [Std.AlphaNumDash ^ 1..63]
data DomainName :: [Hostname ^ 1..0xFF]
data Record :: host Hostname, entry Entry
data Entry :: a IPv4 | aaaa IPv6 | cname DomainName | sub RGBContract.ContractId
Compatibility
Rationale
Reference implementation
schema BaseRegistry implements RGB24
op Register :: registar, entries {registry+} -> registar
!! RegistrationError
self.root => root -> (
let parent = (root.contract !! noRoot).registry
parent.isFullyKnown !! incompleteRoot
let myself = parent.registry.get self.Name !! unregisteredName
myself: Resolve.subdomain(contract) =>
contract =? self.contractId !! selfNotRegistered
)
let registry := self.registry.isFullyKnown !! incompleteRegistry
entries =|> self.registry.has !! repeatedEntry
-- the above is the same as
-- entries => entry -> self.registry.has entry !! repeatedEntry
data RegistrationError ::
noRoot |
unregisteredName |
incompleteRoot |
incompleteRegistry |
selfNotRegistered
