Documentation

codecChainSync Source #

Arguments

:: forall header point tip (m :: Type -> Type). MonadST m
=> (header -> Encoding)	encode header
-> (forall s. Decoder s header)	decode header
-> (point -> Encoding)	encode point
-> (forall s. Decoder s point)	decode point
-> (tip -> Encoding)	encode tip
-> (forall s. Decoder s tip)	decode tip
-> Codec (ChainSync header point tip) DeserialiseFailure m ByteString

Codec for chain sync that encodes/decodes headers, points & tips.

NOTE: See wrapCBORinCBOR and unwrapCBORinCBOR if you want to use this with a header type that has annotations.

codecChainSyncId :: forall header point tip (m :: Type -> Type). Monad m => Codec (ChainSync header point tip) CodecFailure m (AnyMessage (ChainSync header point tip)) Source #

An identity Codec for the ChainSync protocol. It does not do any serialisation. It keeps the typed messages, wrapped in AnyMessage.

byteLimitsChainSync Source #

Arguments

:: (bytes -> Word)	compute size of `bytes`
-> ProtocolSizeLimits (ChainSync header point tip) bytes

Byte Limits

maxChainSyncTimeout :: DiffTime Source #

Chain sync mustReplayTimeout upper bound.

minChainSyncTimeout :: DiffTime Source #

Chain sync mustReplayTimeout lower bound.

data ChainSyncIdleTimeout Source #

ChainSync timeout for the StIdle state, e.g. how long the client can await for MsgRollForward, MsgRollBackward, MsgIntersectFound or MsgIntersectNotFound.
