Functions

func Flatten

func Flatten[S ~[]E, E any](s []S) S

Flatten merges a slice of slices into a single slice.

func GroupByFunc

func GroupByFunc[S ~[]E, E any, K comparable](s S, keyFunc func(E) K) map[K]S

GroupByFunc groups the elements e_1, ..., e_n of s into separate slices by keyFunc(e).

func MapAndGroupByFuncs

func MapAndGroupByFuncs[S ~[]E, E any, K comparable, V any](s S, keyFunc func(E) K, mapFunc func(E) V) map[K][]V

MapAndGroupByFuncs groups the elements e_1, ..., e_n of s into separate slices by keyFunc(e) and then maps those resulting elements by mapFunc(e).

func Partition

func Partition[S ~[]E, E any](s S, n int) []S

Partition partitions the elements of s into n non-overlapping slices, such that some slices have len(s)/n+1 items and some len(s)/n items. Ordering is preserved, such that Flatten(Partition(s)) is equal to s.

func PartitionToMaxLen

func PartitionToMaxLen[S ~[]E, E any](s S, maxLen int) []S

PartitionToLen partitions the elements of s into non-overlapping slices, such that each such slice contains at most maxLen elements.

func Subtract

func Subtract[T comparable](list []T, toRemove []T) []T
