Struct PredictionBuffer 

pub struct PredictionBuffer<I, S> { /* private fields */ }

Bounded client input/state history for server reconciliation.

Implementations

impl<I, S> PredictionBuffer<I, S>

pub fn new(config: PredictionConfig) -> NetcodeResult<Self>

Creates an empty prediction history.

pub fn record( &mut self, tick: u64, input: I, predicted_state: S, ) -> NetcodeResult<()>

Records one successfully simulated local input and resulting state.

pub fn confirmed_tick(&self) -> u64

Returns the highest authoritative Tick already reconciled.

pub fn pending_len(&self) -> usize

Returns the number of inputs awaiting authoritative confirmation.

pub fn is_empty(&self) -> bool

Returns whether no unconfirmed input remains.

pub fn frames(&self) -> impl Iterator<Item = &PredictionFrame<I, S>>

Iterates retained prediction frames in Tick order.

impl<I, S> PredictionBuffer<I, S>

where S: Clone,

pub fn reconcile<Simulate>( &mut self, authoritative_tick: u64, authoritative_state: S, simulate: Simulate, ) -> NetcodeResult<ReconciliationReport<S>>

where Simulate: FnMut(&mut S, u64, &I),

Restores an authoritative state and deterministically replays later local inputs.

simulate owns game rules and must advance state exactly once for the supplied Tick and input. A replay-limit or ordering error leaves the buffer unchanged.

pub fn reset(&mut self, confirmed_tick: u64)

Clears all prediction history and installs a new confirmed Tick.

Trait Implementations
