Functions

func CastFloatInterfaceToFloat

func CastFloatInterfaceToFloat[To FloatNumber](i interface{}) (To, bool)

func CastInterfaceListToFloatList

func CastInterfaceListToFloatList[To FloatNumber](list []interface{}) ([]To, bool)

func CastInterfaceListToIntList

func CastInterfaceListToIntList[To SignedInt | UnsignedInt](list []interface{}) ([]To, bool)

func CastInterfaceToFloatList

func CastInterfaceToFloatList[To FloatNumber](i interface{}) ([]To, bool)

func CastInterfaceToIntList

func CastInterfaceToIntList[To SignedInt | UnsignedInt](i interface{}) ([]To, bool)

func CastInterfaceToStringMap

func CastInterfaceToStringMap[To any, From any](m interface{}) (map[string]To, bool)

func CastList

func CastList[To any, From any](list []From) ([]To, bool)

CastList casts a list of From objects to To, by casting it to an interface{} in between.

func CastList2

func CastList2[To any, From any](list interface{}) ([]To, bool)

CastList2 attempts even harder to cast a list of From object to To, by checking if we might be dealing with a list masquerading as a interface{}, then a []interface{}, before checking for []To.

func CastListToFloatList2

func CastListToFloatList2[To FloatNumber](list interface{}) ([]To, bool)

func CastListToIntList2

func CastListToIntList2[To SignedInt | UnsignedInt](list interface{}) ([]To, bool)

func CastMapMember

func CastMapMember[To any](m map[string]interface{}, k string) (*To, bool)

func CastMapToInterfaceMap

func CastMapToInterfaceMap[From any](m map[string]From) map[string]interface{}

func CastNumberInterfaceToFloat

func CastNumberInterfaceToFloat[To FloatNumber](i interface{}) (To, bool)

func CastNumberInterfaceToInt

func CastNumberInterfaceToInt[To SignedInt | UnsignedInt](i interface{}) (To, bool)

func CastStringMap

func CastStringMap[To any, From any](m map[string]From) (map[string]To, bool)

func CastStringMap2

func CastStringMap2[To any, From any](m interface{}) (map[string]To, bool)

func CastToNumberList

func CastToNumberList[To Number, From Number](list []From) ([]To, bool)

CastToNumberList casts a list of From objects to To. This is useful for transform between different int types, for example.
