Crate cranpose_native 

Shared runtime and native-language bindings for embedding Cranpose in native views.

Cranpose Native

cranpose-native embeds a Cranpose composition in a native host view. Native application authors create a NativeSession, exchange named events, and read frame updates. The session owns a worker for composition state. Framework integrators can use NativeView to mount platform controls inside Cranpose UI.

Create a session

The factory creates content on the session’s worker. The helper below wraps a root UI closure in NativeContent:

use cranpose_native::{NativeContent, NativeSession};
use std::sync::Arc;

fn create_session(root: impl FnMut() + Send + 'static) -> Arc<NativeSession> {
    NativeSession::new(move || NativeContent::new(root))
}

The host drives frame, forwards input with touch or send_event, and calls shutdown when the view leaves the host. A platform adapter can attach a FrameListener and request work from its UI loop. The crate selects the WGPU renderer and embedded fallback font through its cranpose dependency. Cargo feature selection lives on cranpose.

See the NativeSession API, the native demo, the host integration guide and the crate source.

Structs

NativeContent

Application content and commands, created on the component’s owning thread.

NativeEvent

NativeFrame

A presentation update. Empty pixels preserve the currently presented image and slots.

NativeSession

Owns an embedded composition and its worker thread.

NativeSlot

One mounted native child.

Enums

NativeError

A native hosting failure.

TouchPhase

Touch input in logical host coordinates.

WebViewEvent

An event from an embedded browser.

Traits

FrameListener

Wakes a platform view when its composition needs a frame.

Functions

NativeView

Reserves a native child with an application-defined factory and configuration.

SendToHost

Sends an application event to the native host after this composition commits.

WebView

Embeds a website inside the component’s layout bounds.
