func FilterMap ¶

func FilterMap[T models.NamedFilterable](
	g map[string][]T,
	key *string,
	name *string,
	filter string,
	pred func(T) bool,
) map[string][]T

FilterMap returns a map of filtered items from the input map, filtered by key, name, filter, and an optional predicate.

func FilterMapOrAll ¶ added in v0.2.0

func FilterMapOrAll[T models.NamedFilterable](g map[string][]T, filter string) map[string][]T

FilterMapOrAll returns g unchanged when filter is empty, and a filtered copy otherwise. Useful for the common case where callers want "all rows when no filter is set" without conditional plumbing at every callsite.

func FilterSlice ¶

func FilterSlice[T models.NamedFilterable](items []T, name *string, filter string, pred func(T) bool) []T

FilterSlice returns a slice of items that match the filter and name. If pred is non-nil, the item must also satisfy pred(item).

func FindByName ¶

func FindByName[T models.NamedItem](items []T, name string) *T

FindByName returns a pointer to the item with the given name, or nil if not found.

func IsMatch ¶

func IsMatch(item models.Filterable, filter string, ignoreCase bool) bool

IsMatch returns true if the item matches the filter string, optionally ignoring case.

func TruncateSlice ¶ added in v0.4.0

func TruncateSlice[T any](items []T, limit int) []T

TruncateSlice returns items[:limit] when limit > 0 and the slice has more items than the limit; otherwise returns items unchanged. A non-positive limit means "no limit" (matches kubectl --limit=0 convention) so callers can pass an unbound limit through without a special branch.

Truncation always happens AFTER filtering: with the toolkit's fuzzy substring filter being client-side, "filter + limit" only makes sense as "first N matching the filter". Source-side `ListOptions.Limit` would silently break that contract when filter is set (the K8s API returns the first N by its own ordering, only some of which match the filter).
