Functions ¶
func BackendObjectReferenceToKey ¶
func BackendObjectReferenceToKey(backendRef gatewayv1.BackendObjectReference) string
BackendObjectReferenceToKey converts a BackendObjectReferenceToKey to a unique string key. It handles nil pointers by using a consistent placeholder.
func ClearMap ¶
func ClearMap[K comparable, V any](m map[K]V)
Generic function to clear a map in place
func ComparePointers ¶
ComparePointers compares two pointers to any ordered type. It establishes a consistent sort order where nil values come before non-nil values.
It returns:
- -1 if a < b
- 0 if a == b (or both are nil)
- +1 if a > b
func KeyToBackendObjectReference ¶
func KeyToBackendObjectReference(key string) (gatewayv1.BackendObjectReference, error)
KeyToBackendObjectReference converts a string key back to a gatewayv1.BackendObjectReference. It is the inverse of BackendObjectReferenceToKey.
func KeyToParentRef ¶
func KeyToParentRef(key string) (gatewayv1.ParentReference, error)
KeyToParentRef converts a string key back to a gatewayv1.ParentReference. It is the inverse of ParentRefToKey.
func Keys ¶
func Keys[K comparable, V any](src map[K]V) map[K]struct{}
func MapToSortedListByCreationTimestamp ¶
func MapToSortedListByCreationTimestamp[T ObjectWithTimestamp](objects map[types.NamespacedName]T) []T
func NamespaceAsString ¶
func ParentRefToKey ¶
func ParentRefToKey(parentRef gatewayv1.ParentReference) string
ParentRefToKey converts a ParentReference to a unique string key. It handles nil pointers by using a consistent placeholder.
func ParseNamespacedName ¶
func ParseNamespacedName(s string) (types.NamespacedName, error)
ParseNamespacedName parses a "namespace/name" string into a NamespacedName.
func RouteGroupKindsToString ¶
func RouteGroupKindsToString(routesGK []gatewayv1.RouteGroupKind) string
func SetDifference ¶
func SetDifference[K comparable, V any](mapA, mapB map[K]V) map[K]struct{}
SetDifference finds the keys that are in mapA but not in mapB. It works for any map with a comparable key type K and any value type V.
func SetIntersection ¶
func SetIntersection[K comparable, V any](mapA, mapB map[K]V) map[K]struct{}
func SortByCreationTimestamp ¶
func SortByCreationTimestamp[T ObjectWithTimestamp](objects []T)
func StrPtrToString ¶
func StrPtrToString[T stringer](p *T) string
func StringToPtr ¶
func StringToPtr[T stringer](s string) *T
StringToPtr converts a string to a pointer of a string-based type. If the string is the placeholder "_", it returns nil.
Types ¶
type ExtractGVK ¶
type ExtractGVK func(object client.Object) schema.GroupVersionKind
ExtractGVK is a function that extracts the GroupVersionKind (GVK) of a client.object. It will log an error if the GKV cannot be extracted.
func NewExtractGKV ¶
func NewExtractGKV(scheme *runtime.Scheme, logger *slog.Logger) ExtractGVK
NewExtractGKV creates a new MustExtractGVK function using the scheme.
type KeyMap ¶
func (*KeyMap[KEY, VALUE]) DeepCopy ¶
DeepCopy creates a deep copy of the KeyMap. It requires the VALUE type to have a DeepCopy() method.
