Types

type Castable 

type Castable struct {
	PbType_  jen.Code // nolint
	MirType_ jen.Code // nolint
}

Castable is used when the types used by protoc-generated code and Mir-generated code can be directly cast to one another.

func (Castable) MirType 

func (t Castable) MirType() *jen.Statement

func (Castable) PbType 

func (t Castable) PbType() *jen.Statement

func (Castable) Same 

func (t Castable) Same() bool

func (Castable) ToMir 

func (t Castable) ToMir(code jen.Code) *jen.Statement

func (Castable) ToPb

type Error 

type Error struct{}

func (t Error) PbType() *jen.Statement

func (Error) Same

type Field 

type Field struct {
	// The name of the field.
	Name string

	// The information about the type of the field.
	Type Type

	// The type to which the field belongs.
	Parent *Message

	// The protobuf descriptor of the field.
	// The descriptor can be either protoreflect.FieldDescriptor or protoreflect.OneofDescriptor.
	ProtoDesc protoreflect.Descriptor
}

Field represents a field in a protobuf message. Note: oneofs are not considered as fields in the protobuf data module, but are considered as fields here. The reason for that is that oneofs are mapped to fields in the generated Go code.
