APIs
Conditional
-
Conditional[T any](cond bool, trueExpr, falseExpr T) TAn alternative of ternary operator, same of
cond ? trueExpr : falseExpr. -
ConditionalExpr[T any](cond bool, trueExpr, falseExpr func() T) TAn alternative to the conditional (ternary) operator (?:), it'll run expression by the conditional result.
-
Max[T constraints.Ordered](a, b T) TGets the maximum value of two values.
-
Min[T constraints.Ordered](a, b T) TGets the minimum value of two values.
Type
-
IsSameType(v1, v2 any) boolCompares two values' type.
-
IsSameRawType(v1, v2 any) boolCompares two values' type without pointer.
-
TypeOf(v any) stringGets the type of the value represented in string.
-
RawTypeOf(v any) stringGets the type string name without pointer.
-
GetElem(o any) anyGets element without pointer.
Pointer and Value
-
Pointer[T any](v T) *TGets the pointer of a value.
-
func Value[T any](v *T) TGets the value of a pointer, or the zero value of the type if the pointer is nil.
-
ValueWithDefault[T any](v *T, defaultValue T) TGets the value of a pointer, or the default value if the pointer is nil.
-
PointerSlice[T any](v []T) *[]TConverts a slice to a pointer slice.
-
ValueSlice[T any](v *[]T) []TConverts a pointer slice to a slice.
-
PointerMap[K comparable, V any](v map[K]V) map[K]*VConverts a map to a pointer map.
-
ValueMap[K comparable, V any](v map[K]*V) map[K]VConverts a pointer map to a map.

Functions ¶
func Conditional ¶
Conditional is an alternative to the conditional (ternary) operator (?:).
func ConditionalExpr ¶ added in v0.1.1
ConditionalExpr is an alternative to the conditional (ternary) operator (?:), it'll run expression by the conditional result.
func IsSameRawType ¶
IsSameRawType compares two values' type without pointer.
func Max ¶
func Max[T constraints.Ordered](v1, v2 T) T
Max returns the maximum value between v1 and v2.
func Min ¶
func Min[T constraints.Ordered](v1, v2 T) T
Min returns the minimum value between v1 and v2.
func PointerMap ¶
func PointerMap[K comparable, V any](src map[K]V) map[K]*V
PointerMap converts a map of values into a map of pointers.
func PointerSlice ¶
func PointerSlice[T any](src []T) []*T
PointerToSlice converts a slice of values into a slice of pointers.
func Value ¶
func Value[T any](v *T) T
Value returns the value of a pointer, or the zero value of the type if the pointer is nil.
func ValueMap ¶
func ValueMap[K comparable, V any](src map[K]*V) map[K]V
ValueMap converts a map of pointers into a map of values.
func ValueSlice ¶
func ValueSlice[T any](src []*T) []T
ValueSlice converts a slice of pointers into a slice of values.
func ValueWithDefault ¶
func ValueWithDefault[T any](val *T, defaultVal T) T
ValueWithDefault returns the value passed in if it is not nil, otherwise returns the default value.
