pub struct LastSeenMessagesValidator {
    tracked_messages: VecDeque<Option<TrackedEntry>>,
    last_pending_signature: Option<Box<[u8]>>,
}

Validates that the client is properly acknowledging messages sent by the server

Fields

tracked_messages: VecDeque<Option<TrackedEntry>>

last_pending_signature: Option<Box<[u8]>>

Implementations

impl LastSeenMessagesValidator

pub fn new() -> Self

Creates a new validator

pub fn add_pending(&mut self, signature: Option<Box<[u8]>>)

Adds a pending message signature that the client should acknowledge Matches vanilla’s deduplication: only adds if different from last pending message

pub fn tracked_count(&self) -> usize

Gets the number of tracked messages

pub fn apply_offset(&mut self, offset: i32) -> Result<(), String>

Applies an offset (removes old acknowledged messages from tracking)

pub fn apply_update( &mut self, acknowledged: [u8; 3], offset: i32, checksum: u8, ) -> Result<Vec<Box<[u8]>>, String>

Applies an acknowledgement update from the client acknowledged: BitSet of 20 bits indicating which messages in the window are acknowledged offset: How many old messages to remove from the window checksum: Optional checksum for validation (0 = skip checksum)
