Functions

func CopyDefaults

func CopyDefaults(a, b interface{})

CopyDefaults for a from b a and b should be pointers to the same kind of struct

func CopyFrom

func CopyFrom(a, b interface{})

CopyFrom sets the public members of a from b a and b should be pointers to structs a can be a different type from b Only the Fields which have the same name and assignable type on a and b will be set.

func FlattenMap

func FlattenMap(a map[string]interface{}) map[string]interface{}

FlattenMap expand key.subkey to nested map

func IsEmpty

func IsEmpty(v reflect.Value) bool

IsEmpty returns true if value empty

func IsZero

func IsZero(src interface{}) bool

IsZero returns true if struct is zero (not have any defined values)

func Lookup

func Lookup(i interface{}, path string) (reflect.Value, error)

func MergeMap

func MergeMap(a interface{}, b map[string]interface{}) error

MergeMap merges maps

func StructFields

func StructFields(src interface{}) ([]reflect.StructField, error)

StructFields returns slice of struct fields

func URLMap

func URLMap(query string) (map[string]interface{}, error)

URLMap returns map of url query params

func Zero

func Zero(src interface{}) (interface{}, error)

Zero creates new zero interface
