Struct MessagesV1 

pub struct MessagesV1 {
    pub messages: Vec<AuthorizedMessageV1>,
    pub actions_state: MessageActionsState,
}

Fields

messages: Vec<AuthorizedMessageV1>

actions_state: MessageActionsState

Computed state from action messages (not serialized - rebuilt on each delta)

Implementations

impl MessagesV1

pub fn rebuild_actions_state(&mut self)

Rebuild the computed actions state by scanning all action messages.

This method only processes PUBLIC action messages. For private rooms, use rebuild_actions_state_with_decrypted and provide the decrypted content for each private action message.

pub fn rebuild_actions_state_with_decrypted( &mut self, decrypted_content: &HashMap<MessageId, Vec<u8>>, )

Rebuild actions state with decrypted content for private action messages.

For private rooms, the caller should decrypt each private action message and provide the plaintext bytes in decrypted_content, keyed by message ID.

Arguments

• decrypted_content - Map of message_id -> decrypted plaintext bytes for private action messages. Public actions are decoded directly.

pub fn is_edited(&self, message_id: &MessageId) -> bool

Check if a message has been edited

pub fn is_deleted(&self, message_id: &MessageId) -> bool

Check if a message has been deleted

pub fn effective_text(&self, message: &AuthorizedMessageV1) -> Option<String>

Get the effective text content for a message (edited content if edited, original otherwise) Returns the text content as a string, or None if the message is encrypted/undecodable

pub fn reactions( &self, message_id: &MessageId, ) -> Option<&HashMap<String, Vec<MemberId>>>

Get reactions for a message

pub fn display_messages(&self) -> impl Iterator<Item = &AuthorizedMessageV1>

Get all non-deleted, non-action messages for display

Trait Implementations

impl Clone for MessagesV1

fn clone(&self) -> MessagesV1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ComposableState for MessagesV1

type ParentState = ChatRoomStateV1

type Summary = Vec<MessageId>

type Delta = Vec<AuthorizedMessageV1>

type Parameters = ChatRoomParametersV1

fn verify( &self, parent_state: &Self::ParentState, parameters: &Self::Parameters, ) -> Result<(), String>

fn summarize( &self, _parent_state: &Self::ParentState, _parameters: &Self::Parameters, ) -> Self::Summary

fn delta( &self, _parent_state: &Self::ParentState, _parameters: &Self::Parameters, old_state_summary: &Self::Summary, ) -> Option<Self::Delta>

fn apply_delta( &mut self, parent_state: &Self::ParentState, parameters: &Self::Parameters, delta: &Option<Self::Delta>, ) -> Result<(), String>

Applies the specified delta to the current state.

fn merge( &mut self, parent_state: &Self::ParentState, parameters: &Self::Parameters, other_state: &Self, ) -> Result<(), String>

Merges the current state with another state.

impl Debug for MessagesV1

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

Formats the value using the given formatter.

impl Default for MessagesV1

fn default() -> MessagesV1

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MessagesV1

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MessagesV1

fn eq(&self, other: &MessagesV1) -> 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 MessagesV1

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
