Must fails if we cannot construct a TypeValueInfo

func NewTypeValueInfo

func NewTypeValueInfo(in interface{}) (*TypeValueInfo, error)

NewTypeValueInfo creates a new TypeValueInfo

func (TypeValueInfo) AllFields

func (si TypeValueInfo) AllFields() ([]*FieldInfo, error)

AllFields returns all fields.

func (TypeValueInfo) AllFieldsWithTag

func (si TypeValueInfo) AllFieldsWithTag(tagName string) ([]*FieldInfo, error)

AllFieldsWithTag returns all fields with a given tag name.

func (TypeValueInfo) AsReturnType

func (si TypeValueInfo) AsReturnType() string

AsReturnType generates a declaration for si as a return type.

func (TypeValueInfo) AsReturnValue

func (si TypeValueInfo) AsReturnValue(name string) string

AsReturnValue generates a declaration for si as a return value.

func (TypeValueInfo) CanBeNil

func (si TypeValueInfo) CanBeNil() bool

CanBeNil returns whether a declaration of this type can be nil.
