Struct CdcState 

pub struct CdcState {
    pub cursors: HashMap<String, String>,
    pub sent_messages: HashMap<String, Vec<SentMessageRecord>>,
}

Per-channel cursor state for tracking which messages have been processed.

Fields

cursors: HashMap<String, String>

Per-channel cursors (channel_name -> cursor string).

sent_messages: HashMap<String, Vec<SentMessageRecord>>

Message IDs we’ve sent (for reply-chain detection). Maps channel -> Vec.

Implementations

impl CdcState

pub fn load(workspace: &Path) -> Self

pub fn cursor_for(&self, channel: &str) -> Option<&str>

Get the cursor for a specific channel.

pub fn set_cursor(&mut self, channel: &str, cursor: String)

Update the cursor for a channel.

pub fn record_sent(&mut self, channel: &str, message_id: &str)

Record a sent message for reply-chain detection.

pub fn is_reply_to_us(&self, channel: &str, reply_to: &str) -> bool

Check if a message is a reply to one of our sent messages.

pub fn expire_sent_records(&mut self, ttl_days: u64)

Expire sent message records older than ttl_days.
