Struct Slots 

pub struct Slots { /* private fields */ }

The children a component receives from its call site, grouped by slot. A bare child lands in the default slot (None); a child written with slot:"name" lands in that named slot. Inside the component, the children placeholder drains the default slot and children name:"x" drains the "x" slot — each in call-site order. Draining is one-shot: a slot placeholder consumes its children, so referencing the same slot twice yields an empty list the second time.

Implementations

impl Slots

pub fn new() -> Self

pub fn push(&mut self, name: Option<&'static str>, item: Box<dyn LayoutItem>)

pub fn take_default(&mut self) -> Vec<Box<dyn LayoutItem>>

Drains the default (unnamed) children in call-site order.

pub fn take(&mut self, name: &str) -> Vec<Box<dyn LayoutItem>>

Drains the children assigned to the named slot name, in call-site order.
