Struct Behavior 

pub struct Behavior<T> { /* private fields */ }

A time-varying value backed by geometric algebra

Behavior<T> wraps any value type T and stores it internally as a GA3 multivector. This enables:

• Reactive updates with subscriber notification
• Derived behaviors via map and combine
• Geometric transformations under the hood

Example

use cliffy_core::{behavior, Behavior};

let count = behavior(0);
assert_eq!(count.sample(), 0);

count.update(|n| n + 1);
assert_eq!(count.sample(), 1);

Implementations

impl<T: IntoGeometric + FromGeometric + Clone + 'static> Behavior<T>

pub fn new(initial: T) -> Self

Create a new behavior with an initial value

pub fn sample(&self) -> T

Sample the current value

pub fn update<F>(&self, f: F)

where F: FnOnce(T) -> T,

Update the value using a transformation function

The function receives the current value and returns the new value. All subscribers are notified after the update.

pub fn set(&self, value: T)

Set the value directly

pub fn subscribe<F>(&self, callback: F) -> Subscription

where F: Fn(&T) + 'static,

Subscribe to value changes

Returns a Subscription that can be used to unsubscribe.

pub fn map<U, F>(&self, f: F) -> Behavior<U>

where U: IntoGeometric + FromGeometric + Clone + 'static, F: Fn(T) -> U + 'static,

Create a derived behavior by mapping a function over this behavior

The derived behavior will automatically update when this behavior changes.

pub fn combine<U, V, F>(&self, other: &Behavior<U>, f: F) -> Behavior<V>

where U: IntoGeometric + FromGeometric + Clone + 'static, V: IntoGeometric + FromGeometric + Clone + 'static, F: Fn(T, U) -> V + Clone + 'static,

Combine two behaviors into a new behavior

pub fn geometric_state(&self) -> GA3

Get the internal geometric state (for advanced users)

pub fn apply_geometric<F>(&self, transform: F)

where F: FnOnce(&GA3) -> GA3,

Apply a geometric transformation directly (for advanced users)

Trait Implementations

impl<T> Clone for Behavior<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
