Struct Group 

pub struct Group {
    pub id: String,
    pub name: String,
    pub creator_did: String,
    pub epoch: u64,
    pub members: Vec<Member>,
    pub relay_url: String,
    pub slot_id: String,
    pub slot_token: String,
    pub creator_sig: String,
}

Fields

id: String

name: String

creator_did: String

epoch: u64

Bumped on every roster mutation (add/remove). Orders revocations (T17).

members: Vec<Member>

relay_url: String

The shared group-room slot (I2). The creator allocates one relay slot; its token is the room key, distributed only to vouched members. Everyone posts + pulls this one slot. Empty until the room is allocated.

slot_id: String

slot_token: String

Shared room key — read+write bearer credential for the group slot. SECRET: held only by vouched members; a leak compromises the room (revocation = rotate the slot, the I3 kick path).

creator_sig: String

Creator’s Ed25519 signature (base64) over the canonical roster sans this field. Empty until signed.

Implementations

impl Group

pub fn new( id: String, name: String, creator_handle: String, creator_did: String, ) -> Self

New group with the creator as the sole initial member. Unsigned — call Group::sign with the creator’s private key.

pub fn set_room( &mut self, relay_url: String, slot_id: String, slot_token: String, )

Attach the relay-room coords (the shared group slot). Does NOT bump epoch — set as part of the create transaction, before signing.

pub fn set_member_keys( &mut self, did: &str, key_id: String, key: String, ) -> Result<()>

Attach a member’s signing key by DID. Does NOT bump epoch — set as part of the add transaction, before signing. Errors if the DID isn’t present.

pub fn contains_did(&self, did: &str) -> bool

True if did is in the roster (any tier).

pub fn other_member_handles(&self, self_did: &str) -> Vec<String>

Member handles excluding self — the fan-out target for a group send.

pub fn add_member( &mut self, handle: String, did: String, tier: GroupTier, ) -> Result<()>

Add a member at tier. Bumps epoch and INVALIDATES the signature (re-sign before persisting). Errors if the DID is already present.

pub fn remove_member(&mut self, did: &str) -> Result<String>

Remove a member by DID (kick). Bumps epoch (orders the revocation) and invalidates the signature. Refuses to remove the creator. Returns the removed member’s handle.

pub fn sign(&mut self, private_key: &[u8]) -> Result<()>

Sign the roster with the creator’s private key (32-byte seed).

pub fn verify(&self, creator_pubkey: &[u8]) -> bool

Verify creator_sig against the creator’s public key (32 bytes).

Trait Implementations

impl Clone for Group

fn clone(&self) -> Group

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Group

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Group

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Group

fn eq(&self, other: &Group) -> 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 Group

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
