Enum rat_salsa::Control

pub enum Control<Message> {
    Continue,
    Unchanged,
    Changed,
    Message(Message),
    Quit,
}

Result of event-handling.

The macro rat-event::flow! provides control-flow using this enum.

Variants

Continue

Continue with event-handling. In the event-loop this waits for the next event.

Unchanged

Break event-handling without repaint. In the event-loop this waits for the next event.

Changed

Break event-handling and repaints/renders the application. In the event-loop this calls render.

Message(Message)

Handle an application defined event. This calls message to distribute the message throughout the application.

This helps with interactions between parts of the application.

Quit

Quit the application.

impl<Message: Ord> Ord for Control<Message>

fn cmp(&self, other: &Control<Message>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

impl<Message: PartialEq> PartialEq for Control<Message>

fn eq(&self, other: &Control<Message>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
