Trait CollectionWidget

pub trait CollectionWidget<'a, Message: 'a>: Widget<Message, Theme, Renderer>
where
    Self: Sized,
{
    // Required methods
    fn append<E>(self, other: &mut Vec<E>) -> Self
       where E: Into<Element<'a, Message>>;
    fn push(self, element: impl Into<Element<'a, Message>>) -> Self;

    // Provided methods
    fn extend<E>(self, iterator: impl Iterator<Item = E>) -> Self
       where E: Into<Element<'a, Message>> { ... }
    fn push_maybe(
        self,
        element: Option<impl Into<Element<'a, Message>>>,
    ) -> Self { ... }
}

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<'a, Message: 'a> CollectionWidget<'a, Message> for Column<'a, Message>
