IBC tendermint client sentinel errors

var SubModuleCdc *codec.Codec

Functions

func MakeBlockID 

func MakeBlockID(hash []byte, partSetSize int, partSetHash []byte) tmtypes.BlockID

Copied unimported test functions from tmtypes to use them here

func RegisterCodec 

func RegisterCodec(cdc *codec.Codec)

RegisterCodec registers the Tendermint types

func SetSubModuleCodec 

func SetSubModuleCodec(cdc *codec.Codec)

func ValidCommit 

func ValidCommit(chainID string, commit *tmtypes.Commit, valSet *tmtypes.ValidatorSet) (err error)

ValidCommit checks if the given commit is a valid commit from the passed-in validatorset

CommitToVoteSet will panic if the commit cannot be converted to a valid voteset given the validatorset This implies that someone tried to submit evidence that wasn't actually committed by the validatorset thus we should return an error here and reject the evidence rather than panicing.
