Additional methods for the [Column] and [Row] widgets.

Required Methods

fn append<E>(self, other: &mut Vec<E>) -> Self

where E: Into<Element<'a, Message>>,

Moves all the elements of other into self, leaving other empty.

fn push(self, element: impl Into<Element<'a, Message>>) -> Self

Pushes an element into the widget.

Provided Methods

fn extend<E>(self, iterator: impl Iterator<Item = E>) -> Self

where E: Into<Element<'a, Message>>,

Appends all elements in an iterator to the widget.

fn push_maybe(self, element: Option<impl Into<Element<'a, Message>>>) -> Self

Conditionally pushes an element to the widget.
