87 symbols, imported from @driftengine/network.

Classes

AuthorityHost: The machine whose world is the truth.
Fingerprint: An FNV-1a pair, fed bytes and numbers, answering sixteen hex characters.
InputLog
LockstepSession
LoopbackNetwork: A set of endpoints that can reach each other, holding the clock they share.
LoopbackTransport
PredictingClient: A machine that predicts its own player and corrects toward the authority.
RewindLoop
ScriptSession
StateInterpolator: Two authoritative states and where between them to draw.
WebRtcTransport
WebSocketTransport

AuthorityOptions
ClientOptions
DataChannelLike: What an RTCDataChannel satisfies. Declared rather than imported; see websocket.ts.
DecodedMessage: What a decoded message turned out to be. kind 0 means it did not decode.
Desync
FixtureMath: The trigonometry, supplied rather than imported.
FixtureResult
Impairment
InputLogOptions
LockstepOptions
LoopbackOptions
PeerConnectionLike: The part of RTCPeerConnection unreliableChannel needs.
Replicator: What a consumer packs and unpacks.
RewindOptions
SavablePosition: A seeded generator's position.
ScriptSessionOptions
SessionStatus: What a driver tells the façade about itself. Both session classes satisfy the parts they have.
Snapshotter: Somewhere state can be put and taken back.
SocketLike: What a browser WebSocket and a Node ws both satisfy. Named here so neither is imported.
Transport
WebRtcTransportOptions
WebSocketTransportOptions

combineSnapshotters: Several snapshotters as one, saving and restoring in the order given.
createDecoded
createFixture: The pair of arms, sharing one sine table and one starting state.
decode: Read a message's header into out. false when the bytes are not a message this version knows.
encodeAck
encodeFingerprint
encodeInput: Write an input frame into into, answering how many bytes it used, or -1 when it does not fit.
encodeJoin
encodeState
encodeWelcome
fingerprintSnapshot: A world snapshot's fingerprint.
randomSnapshotter: A generator, as one number.
simAbs
simAdd
simCompare: -1, 0 or 1. Present so a caller compares through this file rather than by hand.
simDiv: Divide. Deterministic rather than exact; see §3 of the header. Division by zero saturates.
simFrom: From an ordinary number. Truncates toward negative infinity, as everything here does.
simFromInt: From an integer, exactly, with no rounding to think about.
simMax
simMin
simMul: Multiply. Exact wherever the result is representable; see §2 of the header.
simNeg
simSqrt: Square root, by Newton's method on integers.
simSub
simTo: Back to an ordinary number. Exact: a division by a power of two.
unreliableChannel: A channel configured the way a simulation wants one.
worldSnapshotter: A world, through the identity-preserving snapshot @driftengine/entities owns.

InputPredictor: How a missing input is guessed. previous is that participant's last confirmed input.
LockstepStatus
MessageSink: Where a drained message goes.
PeerId: Which participant a message is for or from. Small integers, assigned by the host.
SessionRole: What a role means is in this file's header, not in these names.
Sim: A fixed-point value: an integer, scaled by SIM_ONE, carried in a double.
SimStep: One fixed step. The signature LoopHooks.simulate has, so a consumer passes theirs straight in.
TransportState

BROADCAST: Send to everyone the transport can reach.
FINGERPRINT_BYTES: A fingerprint message is fixed: kind, participant, tick, and eight bytes of digest.
FIXTURE_BODIES
INPUT_HEADER_BYTES: Header bytes before an input run's payloads: kind, participant, first tick, count, stride.
MESSAGE_ACK
MESSAGE_FINGERPRINT
MESSAGE_INPUT
MESSAGE_JOIN
MESSAGE_PING
MESSAGE_STATE
MESSAGE_WELCOME
PROTOCOL_VERSION: The framing, which is small on purpose.
repeatLastInput: Repeat the last input seen from that participant. See the header for when this is wrong.
SIM_FRACTION_BITS: Fractional bits. The whole format is this number.
SIM_MAX: The largest and smallest representable raws, which is a double's exact integer range.
SIM_MIN
SIM_ONE: One, as a raw value.
STATE_HEADER_BYTES: Header bytes before a state payload: kind, tick, length.
