Struct ReplicaTable 

pub struct ReplicaTable {
    pub entities: BTreeMap<EntityId, ReplicaEntity>,
    pub precision: f32,
    pub spawn_ticks: BTreeMap<EntityId, u64>,
    pub datagram_frames: BTreeMap<EntityId, u64>,
    pub stream_tick: u64,
}

A client’s table of the entities it has been told about.

Fields

entities: BTreeMap<EntityId, ReplicaEntity>

precision: f32

spawn_ticks: BTreeMap<EntityId, u64>

The tick of the stream frame that spawned each entity: a datagram update names it (see crate::datagram). Set only by ReplicaTable::apply_stream.

datagram_frames: BTreeMap<EntityId, u64>

The last datagram applied to each entity (see crate::datagram).

stream_tick: u64

The tick of the last stream frame applied with ReplicaTable::apply_stream. A client on an unreliable transport acks each datagram with it, so the server knows which spawns it had.

Implementations

impl ReplicaTable

pub fn apply_datagram( &mut self, datagram: &[u8], ) -> Result<DatagramSummary, DecodeError>

Apply one datagram. It changes nothing it cannot apply exactly (see DatagramSummary::skipped). An error means the bytes are not a datagram; the table then may hold part of it.

impl ReplicaTable

pub fn new() -> Self

pub fn pos(&self, id: EntityId) -> Option<[f32; 3]>

pub fn apply(&mut self, frame: &[u8]) -> Result<FrameSummary, DecodeError>

Apply one frame. On an error the table may hold part of the frame; the caller should treat the connection as broken.

pub fn apply_stream( &mut self, frame: &[u8], tick: u64, ) -> Result<FrameSummary, DecodeError>

Apply one frame from the stream of a subscription that also gets datagrams, with the tick its header carries. The table records the tick each entity spawned at and the tick of the last stream frame, which datagrams and their acks name. A full frame starts that record over, so frames the server dropped before the client got them, or an earlier connection, leave nothing behind.
