Functions ¶
func CountError ¶
CountError returns the number of elements in s where f returns true.
Returns error the first time f returns error.
func ElementsContained ¶
ElementsContained returns true if superset contains subset.
Nil and empty slices are treated as equals.
func ElementsEqual ¶
func ElementsEqual[T comparable](one []T, two []T) bool
ElementsEqual returns true if the two slices have equal elements.
Nil and empty slices are treated as equals.
func FilterError ¶
FilterError filters the slice to only the values where f returns true.
Returns error the first time f returns error.
func MapToSlice ¶
func MapToSlice[T comparable](m map[T]struct{}) []T
MapToSlice converts the map to a slice.
func MapToSortedSlice ¶
func MapToSortedSlice[M ~map[T]struct{}, T Ordered](m M) []T
MapToSortedSlice converts the map to a sorted slice.
func Reduce ¶
func Reduce[T1, T2 any](s []T1, f func(T2, T1) T2, initialValue T2) T2
Reduce reduces the slice.
func ToChunks ¶
ToChunks splits s into chunks of the given chunk size.
If s is nil or empty, returns empty. If chunkSize is <=0, returns [][]T{s}.
func ToUniqueSorted ¶
func ToUniqueSorted[S ~[]T, T Ordered](s S) S
ToUniqueSorted returns a sorted copy of s with no duplicates.
Types ¶
type Ordered ¶
type Ordered interface {
~int | ~int8 | ~int16 | ~int32 | ~int64 |
~uint | ~uint8 | ~uint16 | ~uint32 | ~uint64 | ~uintptr |
~float32 | ~float64 |
~string
}
Ordered matches cmp.Ordered until we only support Go versions >= 1.21.
TODO: remove and replace with cmp.Ordered when we only support Go versions >= 1.21.
