Supported Types

The following types can be used in dubhe.config.ts for resource field and key definitions.

Primitive types

Vector types

Enum types

Any enum defined in the enums section of dubhe.config.ts can be used as a field or key type by its name string.

enums: {
  Direction: ['North', 'East', 'South', 'West'],
  Status:    ['Idle', 'Fighting', 'Dead']
},
resources: {
  facing:  'Direction',                                         // enum as single value
  unit:    { fields: { pos: 'address', status: 'Status' } },   // enum as field
  combat:  { fields: { attacker: 'address', dir: 'Direction' }, keys: ['attacker'] } // enum as key
}

Enum variants are encoded as u8 indices via BCS. Each enum gets its own Move module with:

• new_<variant>() constructors
• is_<variant>() predicates
• encode(v) / decode(bcs) for BCS serialization

Type notes

• u64, u128, u256 are represented as bigint in TypeScript clients to avoid precision loss.
• String refers to std::ascii::String in Move. Non-ASCII characters are not supported; use vector<u8> for arbitrary bytes.
• address is a 32-byte Sui address. When used as a resource_account parameter, it is passed as a hex-encoded ASCII string (e.g. "0x000...00a").
• vector<u16> is supported in codegen but note that Sui’s BCS does not have a native peel_u16; the codegen handles this via manual byte parsing.
