Enum ContractGroupOwner 

pub enum ContractGroupOwner {
    SingleOwner(Identifier),
    OwnerAndAdmins {
        owner: Identifier,
        admins: BTreeSet<Identifier>,
    },
}

Who owns a contract group, and who may add members to it.

Every group has exactly one owner: the identity that registered it. A member is added by the identity that creates the member contract, so a join is allowed when that identity is the owner or one of the group’s admins. Admins act alone; there is no threshold.

Variants

SingleOwner(Identifier)

One identity owns the group and is the only one who may add members.

OwnerAndAdmins

One identity owns the group and a set of admins may add members alongside it. At least one admin, at most SystemLimits::max_contract_group_admins, none of them the owner.

Fields

owner: Identifier

The owner: the identity that registered the group.

admins: BTreeSet<Identifier>

The identities that may add members besides the owner.

Implementations

impl ContractGroupOwner

pub fn owner_id(&self) -> &Identifier

The identity that owns the group.

pub fn admin_ids(&self) -> Option<&BTreeSet<Identifier>>

The identities that may add members besides the owner. Empty for a single owner.

pub fn admin_count(&self) -> usize

The number of admins.

pub fn may_add_members(&self, identity_id: &Identifier) -> bool

Whether identity_id may add members to the group: the owner or an admin.

Trait Implementations

Attempt to decode this type with the given BorrowDecode.

impl<'__de, __Context> BorrowDecodeUntrusted<'__de, __Context> for ContractGroupOwner

fn borrow_decode_untrusted<__D: BorrowUntrustedDecoder<'__de, Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Borrow-decode with explicit untrusted field dispatch and resource handling.

impl Clone for ContractGroupOwner

fn clone(&self) -> ContractGroupOwner

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ContractGroupOwner

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<__Context> Decode<__Context> for ContractGroupOwner

fn decode<__D: Decoder<Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given Decode.

impl<__Context> DecodeUntrusted<__Context> for ContractGroupOwner

fn decode_untrusted<__D: UntrustedDecoder<Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Decode with explicit untrusted field dispatch and resource handling.

impl<'de> Deserialize<'de> for ContractGroupOwner

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ContractGroupOwner

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Encode for ContractGroupOwner

fn encode<__E: Encoder>(&self, encoder: &mut __E) -> Result<(), EncodeError>

Encode a given type.

impl Eq for ContractGroupOwner

impl PartialEq for ContractGroupOwner

fn eq(&self, other: &ContractGroupOwner) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ContractGroupOwner

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
