Functions

func TryCast

func TryCast[T any](v any) (T, bool)

TryCast works similar to `v2, ok := v.(T)` Except it works through type alias'

func TryCastType

func TryCastType(v any, dest reflect.Type) (any, bool)

func Underlying

func Underlying(t reflect.Type) (ret reflect.Type)

Underlying returns the underlying type of t (without type alias)

Types

type PrimitiveStringSerializer

type PrimitiveStringSerializer struct{}

PrimitiveStringSerializer is used to serialize primitive types (and a few more) from and to string This is not really intended to be user facing, and more as a simple building block for other mechanisms supports:

• golang primitives (ints, uints, floats, bool, string)
• type aliases
• time.Time
• primitive.ObjectID

func (PrimitiveStringSerializer) ValueFromString

func (pss PrimitiveStringSerializer) ValueFromString(str string, outType reflect.Type) (any, error)

func (PrimitiveStringSerializer) ValueToString

func (pss PrimitiveStringSerializer) ValueToString(v any) (string, error)
