Struct ActivatableRegion 

pub struct ActivatableRegion {
    pub effect: EphemeralOpaque<dyn Fn() + Send + Sync>,
}

A region of a Space that does something if Tool::Activate is used on it.

TODO: This is a placeholder for a better design; it’s too specific (external side effect) and yet also not general enough (we would like buttons to have detailed reactions to clicking) considering that it’s hardcoded in Space.

Fields

effect: EphemeralOpaque<dyn Fn() + Send + Sync>

The function to call when this region is activated.

Implementations

impl ActivatableRegion

pub fn activate(&self)

Activate this region, calling the embedded function.

Trait Implementations

impl Behavior<Space> for ActivatableRegion

fn step(&self, _context: &Context<'_, '_, Space>) -> (UniverseTransaction, Then)

Computes a transaction to apply the effects of this behavior for one timestep, and specifies when next to step the behavior again (if ever).

fn persistence(&self) -> Option<Persistence>

If None, then the behavior should not be persisted/saved to disk, because it will be reconstructed as needed (e.g. collision, occupancy, user interaction, particles).

impl Clone for ActivatableRegion

fn clone(&self) -> ActivatableRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActivatableRegion

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ActivatableRegion

fn eq(&self, other: &ActivatableRegion) -> bool

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl VisitHandles for ActivatableRegion

fn visit_handles(&self, _: &mut dyn HandleVisitor)

For each Handle contained within self that is reachable without traversing another Handle, call visitor with a reference to it.

impl Eq for ActivatableRegion
