Documentation

data Effect tx Source #

Analogous to inputs, the pure head logic "core" can have effects emited to the "shell" layers and we distinguish the same: effects onto the client, the network and the chain.

Constructors

ClientEffect	Effect to be handled by the Hydra.API, results in sending this `ServerOutput`.
Fields serverOutput :: ServerOutput tx
NetworkEffect	Effect to be handled by a Hydra.Network, results in a `broadcast`.
Fields message :: Message tx
OnChainEffect	Effect to be handled by a Hydra.Chain, results in a `postTx`.
Fields postChainTx :: PostChainTx tx
