Types

type Generator

type Generator interface {
	NewMapper(structInstance interface{}) (*Mapper, error)
}

Generator is an interface for creating a mapper

type JSONGenerator

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

JSONGenerator is a generator for JSON mappers

func NewJSONGenerator

func NewJSONGenerator(logger *Logger) *JSONGenerator

NewJSONGenerator creates a new JSON generator

func (*JSONGenerator) NewMapper

func (j *JSONGenerator) NewMapper(structInstance interface{}) (
	*Mapper,
	error,
)

type Logger

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

Logger is the JWT validator logger

func NewLogger

func NewLogger(header string, modeLogger gologgermode.Logger) (*Logger, error)

func (*Logger) PrintField

func (l *Logger) PrintField(
	structName string,
	fieldName string,
	fieldType reflect.Type,
)

PrintField prints a field

type Mapper

type Mapper struct {
	// Fields key is the field name and value is the name used in the validation error
	Fields map[string]string

	// NestedMappers key is the field name of the nested struct and value is the nested mapper
	NestedMappers map[string]*Mapper
}

Mapper is a map of fields to validate from a struct

type ProtobufGenerator
