Functions

func CollInterfaceValue added in v0.50.0

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(cdc JSONCodec, toPrint proto.Message) ([]byte, error)

MarshalYAML marshals toPrint using JSONCodec to leverage specialized MarshalJSON methods (usually related to serialize data with protobuf or amin depending on a configuration). This involves additional roundtrip through JSON.

Types

type AminoCodec deprecated

type AminoCodec struct {
