Struct ScriptRuntime

Source

pub struct ScriptRuntime { /* private fields */ }

Expand description

Native script instance lifecycle and per-instance panic isolation. A panic disables only the affected instance until it is recreated or reloaded.

Implementations§

Source §

impl ScriptRuntime

Source

pub fn host(&self) -> Option<&ScriptHost>

Current native host, if a scripts library is loaded.

Source

pub fn instance_count(&self) -> usize

Number of instantiated attached scripts, including disabled instances.

Source

pub fn failed_count(&self) -> usize

Disabled callback instances plus slots whose initialization failed.

Source

pub fn restart_instances(&mut self)

Drops all instances and failure records while retaining the host. The next sync reconstructs scripts from serialized slot properties.

Source

pub fn set_host(&mut self, host: Option<ScriptHost>)

Replaces the library (hot reload). All instances are recreated by the next sync.

Source

pub fn sync(&mut self, scene: &Scene, log: &mut Vec<String>)

Creates instances for newly attached scripts and drops those of removed entities.

Source

pub fn run( &mut self, phase: Phase, scene: &mut Scene, physics: &Physics, input: &Input, time: Time, log: &mut Vec<String>, )

Runs attached instances in creation order, catching callback panics. Slots removed earlier in this frame do not receive further callbacks.

where T: 'static + ?Sized,

Source §

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

Source §

impl<T> Borrow<T> for T
where T: ?Sized,

Source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

§

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.

§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Converts Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

§

fn as_any(&self) -> &(dyn Any + 'static)

Converts &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Converts &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

Source §

impl<T> From<T> for T

Source §

fn from(t: T) -> T

Returns the argument unchanged.

Source §

impl<T, U> Into for T
where U: From<T>,

Source §

fn into(self) -> U

Calls U::from(self).
