func GetStructField ¶

func GetStructField(structure any, fieldName string) (any, bool)

GetStructField checks if the given structure has a given field. The structure should be passed by reference. It returns an interface and a boolean, the field's content and a boolean denoting whether or not the field exists. If the boolean is false then there is no such field on the structure. If the boolean is true but the interface stores "" then the field exists but is not set. If the boolean is true and the interface is not empty, the field exists and is set.

func GetStructureField ¶

func GetStructureField(field reflect.Value) any

func GetUnexportedStructureField ¶

func GetUnexportedStructureField(structure any, fieldName string) any

func InheritsFrom ¶

func InheritsFrom(object any, parentType reflect.Type) bool

InheritsFrom uses reflection to find if a struct "inherits" from a certain type. In other words it checks whether the struct embeds a struct of that type.

func IsEmpty ¶ added in v1.4.2

func IsEmpty(value any) bool

IsEmpty checks whether a value is empty i.e. "", nil, 0, [], {}, false, etc. For Strings, a string is considered empty if it is "" or if it only contains whitespaces

func SetStructField ¶

func SetStructField(structure any, fieldName string, value any) error

SetStructField attempts to set a field of a structure to the given value It returns nil or an error, in case the field doesn't exist on the structure or the value and the field have different types

func SetStructureField ¶

func SetStructureField(field reflect.Value, value any)

func SetUnexportedStructureField ¶

func SetUnexportedStructureField(structure any, fieldName string, value any)

func ToStructPtr ¶ added in v1.8.0

func ToStructPtr(obj reflect.Value) (val any, err error)

ToStructPtr returns an instance of the pointer (interface) to the object obj.
