Struct RenderSlot 

pub struct RenderSlot { /* private fields */ }

Owned UI content expanded by its parent during a Tessera build.

The parent decides whether, when, and where content expands. Captures must be owned, Send, Sync, and static; capture stable State handles for changing data.

Stored content owns its captures. Move local values into its closure:

use tessera_ui::{RenderSlot, tessera};

#[tessera]
fn host(child: Option<RenderSlot>) {}

#[tessera]
fn app() {
    let label = String::from("Title");
    host().child(|| { let _ = label.len(); });
}

A configuration handle cannot be used in place of deferred child content:

use tessera_ui::{RenderSlot, tessera};

#[tessera]
fn host(child: Option<RenderSlot>) {}

#[tessera]
fn leaf() {}

#[tessera]
fn app() {
    host().child(leaf());
}

Implementations

impl RenderSlot

pub fn new<F, Output>(render: F) -> Self

where F: Fn() -> Output + Send + Sync + 'static,

Create a render slot from a closure.

This must be called during a component build.

pub const fn empty() -> Self

Create an empty render slot.

pub fn render(&self)

Expands the content at the current build position.

Call this only from a component or recognized build closure.
