Functions

func MarshalJSONIndent 

func MarshalJSONIndent(cdc *LegacyAmino, obj interface{}) ([]byte, error)

MarshalJSONIndent provides a utility for indented JSON encoding of an object via an Amino codec. It returns an error if it cannot serialize or indent as JSON.

func MarshalYAML

func MustMarshalJSONIndent(cdc *LegacyAmino, obj interface{}) []byte

MustMarshalJSONIndent executes MarshalJSONIndent except it panics upon failure.

func ProtoMarshalJSON 

func ProtoMarshalJSON(msg proto.Message, resolver jsonpb.AnyResolver) ([]byte, error)

func RegisterEvidences 

func RegisterEvidences(cdc *LegacyAmino)

RegisterEvidences registers Tendermint evidence types with the provided Amino codec.
