Struct ConversationView 

pub struct ConversationView {
    pub peer: String,
    pub messages: VecDeque<Message>,
    pub scroll_offset: usize,
    pub loaded_count: usize,
    pub total_count: Option<usize>,
    pub is_loading: bool,
    pub has_more_history: bool,
    pub oldest_timestamp: Option<u64>,
    pub newest_timestamp: Option<u64>,
}

Manages a conversation with message history.

This struct handles lazy loading of message history with infinite scrolling. Messages are stored in a VecDeque for efficient prepending when loading older messages.

Fields

peer: String

Username of the peer

messages: VecDeque<Message>

Message cache (ordered by timestamp, oldest first)

scroll_offset: usize

Current scroll position (0 = bottom/newest)

loaded_count: usize

Total messages loaded from storage

total_count: Option<usize>

Total messages in storage (if known)

is_loading: bool

Whether we’re currently loading history

has_more_history: bool

Whether more history exists to load

oldest_timestamp: Option<u64>

Timestamp of oldest loaded message

newest_timestamp: Option<u64>

Timestamp of newest loaded message

Implementations

impl ConversationView

pub fn new(peer: String) -> Self

Create a new conversation view for a peer.

pub fn prepend_messages(&mut self, messages: Vec<Message>)

Add messages to the front (older messages).

Used when loading history backwards in time.

pub fn append_messages(&mut self, messages: Vec<Message>)

Add messages to the back (newer messages).

Used when initially loading recent messages or when receiving new messages.

pub fn add_message(&mut self, message: Message)

Add a single new message (for real-time incoming messages).

pub fn get_oldest_timestamp(&self) -> Option<u64>

Get oldest timestamp for pagination.

pub fn is_at_top(&self) -> bool

Check if we’re scrolled to the top.

pub fn is_at_bottom(&self) -> bool

Check if we’re scrolled to the bottom.
