map

map[origin: ImmutOrigin, IterableType: Iterable, ResultType: Copyable, //, function: def(var IterableType.IteratorType[False, origin._mlir_origin, origin].Element) -> ResultType](ref[origin] iterable: IterableType) -> _MapIterator[function]

Returns an iterator that applies function to each element of the input iterable.

Examples:

var l = [1, 2, 3]
def add_one(x: Int) -> Int:
    return x + 1
var m = map[add_one](l)

# outputs:
# 2
# 3
# 4
for elem in m:
    print(elem)

Parameters:

• ​origin (ImmutOrigin): The origin of the iterable.
• ​IterableType (Iterable): The type of the iterable.
• ​ResultType (Copyable): The return type of the function.
• ​function (def(var IterableType.IteratorType[False, origin._mlir_origin, origin].Element) -> ResultType): The function to apply to each element.

Args:

• ​iterable (IterableType): The iterable to map over.

Returns:

_MapIterator: A map iterator that yields the results of applying function to each element.

map[IterableType: IterableOwned, ResultType: Copyable, //, function: def(var IterableType.IteratorOwnedType.Element) -> ResultType](var iterable: IterableType) -> _MapIterator[function]

Returns an iterator that applies function to each element of the input iterable, consuming the iterable.

Parameters:

• ​IterableType (IterableOwned): The type of the iterable.
• ​ResultType (Copyable): The return type of the function.
• ​function (def(var IterableType.IteratorOwnedType.Element) -> ResultType): The function to apply to each element.

Args:

• ​iterable (IterableType): The iterable to consume and map over.

Returns:

_MapIterator: A map iterator that yields the results of applying function to each element.
