final class NonEmptyMap[K, V] extends AnyRef
A non-empty wrapper for the scala immutable map. Note - this does not attempt to implement all features of map but what the author considers to be the "normal ones".

NonEmptyMap
with an additional element, unless the element is already present.- elem
the element to be added
- returns
a new map that contains all elements of this map and that also contains
elem
.
- def ++(elems: Iterable[(K, V)]): NonEmptyMap[K, V]
Creates a new
NonEmptyMap
by adding all elements contained in another collection to thisNonEmptyMap
, omitting duplicates.Creates a new
NonEmptyMap
by adding all elements contained in another collection to thisNonEmptyMap
, omitting duplicates.This method takes a collection of elements and adds all elements, omitting duplicates, into
NonEmptyMap
.Example:
scala> val a = NonEmptyMap(1, 2) ++ NonEmptyMap(2, "a") a: zio.prelude.NonEmptyMap[Any] = NonEmptyMap(1, 2, a)
- elems
the collection containing the elements to add.
- returns
a new
NonEmptyMap
with the given elements added, omitting duplicates.
