Struct ScreenHandle 

pub struct ScreenHandle<V> { /* private fields */ }

A cloneable, thread-safe handle to a registered screen’s view model.

Implementations

impl<V: ViewModel> ScreenHandle<V>

pub fn update(&self, f: impl FnOnce(&mut V) + Send + 'static)

Changes the view model from any thread (a network handler, a command, …). Queued: runs on the render thread before the next frame or event, then the bindings update. Never blocks.

pub fn read<R>(&self, f: impl FnOnce(&V) -> R) -> Option<R>

Reads the view model — None while the screen is busy (rendering or handling input, e.g. when called from one of its own commands).

pub fn id(&self) -> &'static str

The screen’s UI id.

pub fn open(&self)

Opens the screen.

pub fn close(&self)

Closes the screen if it’s open.

Trait Implementations

fn clone_from(&mut self, source: &Self)
