APIs

Conditional

• Conditional[T any](cond bool, trueExpr, falseExpr T) T

  An alternative of ternary operator, same of cond ? trueExpr : falseExpr.

• ConditionalExpr[T any](cond bool, trueExpr, falseExpr func() T) T

  An alternative to the conditional (ternary) operator (?:), it'll run expression by the conditional result.

• Max[T constraints.Ordered](a, b T) T

  Gets the maximum value of two values.

• Min[T constraints.Ordered](a, b T) T

  Gets the minimum value of two values.

Type

• IsSameType(v1, v2 any) bool

  Compares two values' type.

• IsSameRawType(v1, v2 any) bool

  Compares two values' type without pointer.

• TypeOf(v any) string

  Gets the type of the value represented in string.

• RawTypeOf(v any) string

  Gets the type string name without pointer.

• GetElem(o any) any

  Gets element without pointer.

Pointer and Value

• Pointer[T any](v T) *T

  Gets the pointer of a value.

• func Value[T any](v *T) T

  Gets the value of a pointer, or the zero value of the type if the pointer is nil.

• ValueWithDefault[T any](v *T, defaultValue T) T

  Gets the value of a pointer, or the default value if the pointer is nil.

• PointerSlice[T any](v []T) *[]T

  Converts a slice to a pointer slice.

• ValueSlice[T any](v *[]T) []T

  Converts a pointer slice to a slice.

• PointerMap[K comparable, V any](v map[K]V) map[K]*V

  Converts a map to a pointer map.

• ValueMap[K comparable, V any](v map[K]*V) map[K]V

  Converts a pointer map to a map.
