type CFInvalidVerifiableChunk 

type CFInvalidVerifiableChunk struct {
	// contains filtered or unexported fields
}

CFInvalidVerifiableChunk is returned when a verifiable chunk is invalid this includes cases that code fails to construct a partial trie, collection hashes doesn't match TODO break this into more detailed ones as we progress

func NewCFInvalidVerifiableChunk 

func NewCFInvalidVerifiableChunk(reason string, err error, chInx uint64, execResID flow.Identifier) *CFInvalidVerifiableChunk
