NonEmptyCollection

Combines two structures by taking the union of their shapes and using Ior to hold the elements.

Combines two structures by taking the union of their shapes and combining the elements with the given function.

Returns an element as Some at the given index or None if the index is out of bounds of this iterable.

Returns the first element as Some, or None if the iterable is empty.

Returns the first element as Some matching the given predicate, or None if element was not found.

Flatten an Iterable of Either. Alias for mapOrAccumulate over an Iterable of computed Either. Either returns a List containing all Either.Right values, or a NonEmptyList of all Either.Left values.

Flatten an Iterable of Either. Alias for mapOrAccumulate over an Iterable of computed Either. Either returns a List containing all Either.Right values, or a NonEmptyList of all EitherNel values.

Flatten an Iterable of Either. Alias for mapOrAccumulate over an Iterable of computed Either. Either returns a List containing all Either.Right values, or Either.Left values accumulated using combine.

Flatten an Iterable of Either. Alias for mapOrAccumulate over an Iterable of computed Either. Either returns a List containing all Either.Right values, or EitherNel values accumulated using combine.

Interleaves the elements of this Iterable with those of other. Elements of this and other are taken in turn, and the resulting list is the concatenation of the interleaved elements. If one Iterable is longer than the other, the remaining elements are appended to the end.

Returns the last element as Some, or None if the iterable is empty.

Returns the last element as Some matching the given predicate, or None if no such element was found.

Returns a List containing the zipped values of the two lists with null for padding on the left.

Returns a List containing the result of applying some transformation (A?, B) -> C on a zip, excluding all cases where the right value is null.

Returns Either a List containing the results of applying the given transform function to each element in the original collection, or accumulate all the logical errors into a NonEmptyList that were raised while applying the transform function.

Returns Either a List containing the results of applying the given transform function to each element in the original collection, or accumulate all the logical errors that were raised while transforming the collection using the combine function is used to accumulate all the logical errors.

Returns a List containing the zipped values of the two lists with null for padding.

Returns a List containing the result of applying some transformation (A?, B?) -> C on a zip.

Returns a List> containing the zipped values of the two lists with null for padding on the right.

Returns a List containing the result of applying some transformation (A, B?) -> C on a zip, excluding all cases where the left value is null.

Separate the inner Either values into the Either.Left and Either.Right.

Applies a function f to each element and returns a pair of arrays: the first one made of those values returned by f that were wrapped in Either.Left, and the second one made of those wrapped in Either.Right.

splits a union into its component parts.

Returns single element as Some, or None if the iterable is empty or has more than one element.

Returns the single element as Some matching the given predicate, or None if element was not found or more than one element was found.

Attempt to split the Iterable into the tail and the first element. Returns null if the Iterable is empty, otherwise returns a Pair of the tail and the first element.

Alias for drop(1)

interleaves the elements produced by applying ffa to every element of this Iterable.
