Expand description

A force field with lifecycle metadata.

Fields§

§id: FieldId§field: ForceField§ttl: Option<f32>

None = permanent, Some(seconds) = expires after this duration.

§age: f32

Seconds this field has been alive.

§tags: Vec<String>

Tags for grouping/query filtering.

§strength_scale: f32

Strength multiplier — can be faded over time.

§fade_in: f32

Fade-in duration (ramps strength from 0 to 1 over this time).

§fade_out: f32

Fade-out duration (ramps strength from 1 to 0 before expiry).

Implementations§

Source §

impl ManagedField

Source

pub fn is_expired(&self) -> bool

Whether this field has exceeded its TTL.

Source

pub fn effective_scale(&self) -> f32

Effective strength multiplier accounting for fade-in and fade-out.

Source

pub fn has_tag(&self, tag: &str) -> bool

Returns whether this field has a specific tag.

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

Source §

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

Source §

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

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

Source §

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

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

Source §

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

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

Source §

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

Convert &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> DowncastSync for T
where T: Any + Send + Sync,

Source §

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
