Member Function Documentation

clear()

void InputRingBuffer::clear ( )

inlinenoexcept

Drop everything (used on disconnect / reset).

find()

const InputSnapshot * InputRingBuffer::find ( uint32_t tick ) const

inlinenodiscard

Find the input stamped with exactly tick.

Returns

Pointer into the ring (valid until next push), or nullptr if missing.

Here is the caller graph for this function:

push()

void InputRingBuffer::push ( uint32_t tick, const InputSnapshot & input )

inline

Push the input that was just stamped + sent for tick.

size()

size_t InputRingBuffer::size ( ) const

inlinenodiscardnoexcept

Number of valid entries currently buffered (≤ k_capacity).

Member Data Documentation

count_

size_t InputRingBuffer::count_ = 0

private

Number of valid entries; saturates at k_capacity.

entries_

std::array<Entry, k_capacity> InputRingBuffer::entries_ {}

private

head_

size_t InputRingBuffer::head_ = 0

private

Next write index, wraps mod k_capacity.

k_capacity

size_t InputRingBuffer::k_capacity = 256

staticconstexpr

Capacity in ticks.

Sized for ≥1 RTT of replay buffer at any reasonable RTT; oversize is safer than too-small (replay just stops early if history runs out).
