Variables ¶
var StringUnspecified = "\x00unspecified"
StringValue is the type for sentinel string pattern. The sentinel "\x00unspecified" is used when empty string is meaningful.
Functions ¶
func EqualString ¶ added in v0.1.65
func EqualString(a, b StringValue) bool
9. Equal - equality check (package-level function)
func IsSpecifiedString ¶ added in v0.1.65
func IsSpecifiedString(s StringValue) bool
2. IsSpecified - predicate (package-level function)
func IsUnspecifiedString ¶ added in v0.1.65
func IsUnspecifiedString(s StringValue) bool
IsUnspecifiedString - convenience predicate
func SameString ¶ added in v0.1.65
func SameString(a, b StringValue) bool
7. Same - identity (package-level function)
func SemanticEqualString ¶ added in v0.1.65
func SemanticEqualString(a, b StringValue) bool
8. SemanticEqual - semantic equality (package-level function) For strings, this is the same as Same
func StringString ¶ added in v0.1.65
func StringString(s StringValue) string
5. String - stringification (package-level function)
func TakeOrElse ¶
func TakeOrElse[T comparable](a, b, unspecified T) T
unspecified is the sentinel value
func TakeOrElsePointer ¶
func TakeOrElsePointer[T any](a, b, unspecified *T) *T
golang interface or pointer receiver
func TakeOrElseValue ¶
func TakeOrElseValue[T interface{ IsSpecified() bool }](a, b T) T
Generic TakeOrElse for any type with IsSpecified() method golang interface or value receiver DO NOT PASS NIL as arguments
Types ¶
type Sentinel ¶
type Sentinel interface {
IsSpecified() bool
// contains filtered or unexported methods
}
Do not implement this interface on complex objects value classes inline to primitives, and Unspecified is just the zero bit pattern.
type StringValue ¶ added in v0.1.65
type StringValue = string
func CopyString ¶ added in v0.1.65
func CopyString(s StringValue) StringValue
10. Copy - identity for immutable value types (package-level function)
func MergeString ¶ added in v0.1.65
func MergeString(a, b StringValue) StringValue
4. Merge - composition merge (package-level function) Prefers incoming specified values over current values
func TakeOrElseString ¶
func TakeOrElseString(a, b StringValue) StringValue
3. TakeOrElse - 2-param fallback (package-level function)
