Trait ChildrenExt 

pub trait ChildrenExt: Sized {
    // Required method
    fn get_children(&mut self) -> &mut Vec<Element>;

    // Provided methods
    fn children(self, children: impl IntoIterator<Item = Element>) -> Self { ... }
    fn maybe_child<C>(self, child: Option<C>) -> Self
       where C: IntoElement { ... }
    fn child<C>(self, child: C) -> Self
       where C: IntoElement { ... }
}

Trait for composing child elements.

Required Methods

fn get_children(&mut self) -> &mut Vec<Element>

Returns a mutable reference to the internal children vector.

Example

impl ChildrenExt for MyElement {
    fn get_children(&mut self) -> &mut Vec<Element> {
        &mut self.elements
    }
}

Provided Methods

fn children(self, children: impl IntoIterator<Item = Element>) -> Self

Extends the children with an iterable of Elements.

Example

rect().children(["Hello", "World"].map(|t| label().text(t).into_element()))

fn maybe_child<C>(self, child: Option<C>) -> Self

where C: IntoElement,

Appends a child only when the Option is Some.

Example

rect().maybe_child(show_badge.then(|| label().text("New")))

fn child<C>(self, child: C) -> Self

where C: IntoElement,

Appends a single child element.

Example

rect().child(label().text("Hello"))

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.
