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 CastListToInterfaceList

func CastListToInterfaceList(value interface{}) ([]interface{}, error)

CastListToInterfaceList attempts to convert the given value to a list of interface{}.

The function checks if the provided value is a slice or an array. If so, it returns a slice of interface{}, where each item in the original slice or array is converted to its interface{} representation.

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.

func ConvertMapToInterfaceMap

func ConvertMapToInterfaceMap(input interface{}) (map[string]interface{}, error)

func GetAndCast

func GetAndCast[T any](ps map[string]interface{}, name string, default_ T) (T, bool, error)

func GetAndCastPtr

func GetAndCastPtr[T any](ps map[string]interface{}, name string, default_ *T) (*T, bool, error)

func InterfaceAddr

func InterfaceAddr[T any](t T) *interface{}

func ToInterfaceValue

func ToInterfaceValue(value interface{}) (interface{}, error)

ToInterfaceValue converts a given value of any basic Go type (scalars, slices, arrays, maps) into a corresponding interface{}. Scalar types are returned as is. Slices and arrays are converted to []interface{} with each element being recursively processed. Maps are converted to map[string]interface{} with each value being recursively processed. The function uses reflection to handle various types dynamically. It returns an error if it encounters a type that it cannot process, or if map keys are not strings.
