Fields

configuration: AuthorizedConfigurationV1

Configures things like maximum message length, can be updated by the owner.

bans: BansV1

A list of recently banned members, a banned member can’t be present in the members list and will be removed from it ifc necessary.

members: MembersV1

The members in the chat room along with who invited them

member_info: MemberInfoV1

Metadata about members like their nickname, can be updated by members themselves.

secrets: RoomSecretsV1

Secret distribution for private rooms. Must come before recent_messages so message validation can check secret version consistency.

recent_messages: MessagesV1

The most recent messages in the chat room, the number is limited by the room configuration.

direct_messages: DirectMessagesV1

In-room encrypted direct messages between members (#230 Phase 1). #[serde(default)] keeps states written before this field was added backwards-compatible.

upgrade: OptionalUpgradeV1

If this contract has been replaced by a new contract this will contain the new contract address. This can only be set by the owner.

version: StateVersion

State format version for migration compatibility. Defaults to 0 for backward compatibility with states created before versioning.

Implementations

impl ChatRoomStateV1

pub fn post_apply_cleanup( &mut self, parameters: &ChatRoomParametersV1, ) -> Result<(), String>

Post-apply cleanup: prune members who have no recent messages, clean up member_info for pruned members, remove orphaned bans, and sweep direct messages whose participants are no longer in the room.

Members are kept if they have at least one message in recent_messages, are a sender/recipient of a currently-held direct message (see crate::room_state::direct_messages::DirectMessagesV1::active_participants), or are in the invite chain of someone who qualifies. The owner is never in the members list (they’re implicit via parameters).

Bans are only removed if the banner was themselves BANNED (orphaned ban). If the banner was merely pruned for inactivity, their bans persist.

Direct-message sweep: after pruning, any DM whose sender or recipient is now non-member or banned is dropped. Without this, adding a ban for a DM participant would silently make every peer’s verify fail, and members referenced only by a DM would be pruned (orphaning their DMs). See direct_messages.rs module docs, “Interaction with bans”.

Trait Implementations

impl Clone for ChatRoomStateV1

fn clone(&self) -> ChatRoomStateV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for ChatRoomStateV1

fn default() -> ChatRoomStateV1

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ChatRoomStateV1

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ChatRoomStateV1

fn eq(&self, other: &ChatRoomStateV1) -> bool

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

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