Struct EventGraph 

pub struct EventGraph(/* private fields */);

This manages the graph. The event function is the entrypoint to most graph interactions.

Implementations

impl EventGraph

pub fn new() -> EventGraph

pub fn event<R>( &self, f: impl FnOnce(&mut ProcessingContext<'_>) -> R, ) -> Option<R>

This is a wrapper that runs the event graph after the callback finishes. You should call this whenever an event happens (user input, remote notification, etc) as well as during initial setup, and do all graph manipulation from within the callback.

If this is called re-entrantly, the latter invocation will be ignored (the callback) won’t be run and it will return None.

Trait Implementations

impl Clone for EventGraph

fn clone(&self) -> EventGraph

Returns a duplicate of the value.

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

Performs copy-assignment from source.
