Crate auralis_signal 

auralis-signal: Reactive signal primitive with version tracking and proactive waker deregistration.

Overview

This crate provides Signal<T> and Memo<T> — the foundational reactive primitives of the Auralis kernel. Every signal carries a monotonic version number. When a change-detection future is dropped before resolution, it eagerly removes its waker from the signal’s internal list, preventing stale-waker accumulation (the “proactive deregistration” guarantee).

The crate is zero-dependency, #![forbid(unsafe_code)], and intentionally single-threaded (!Send / !Sync). See the repository design docs for the rationale behind those choices.

Quick example

use auralis_signal::Signal;

let sig = Signal::new(0);
sig.set(1);
assert_eq!(sig.read(), 1);

Macros

memo

Create a Memo with automatic clone of captured identifiers.

Structs

FilterChangedFuture

A Future that yields a new signal value only when it satisfies a predicate.

MapChangedFuture

A Future that transforms each new signal value through a mapping function.

Memo

A lazy, auto-tracking computed signal.

Signal

A reactive value container with monotonic version tracking.

SignalChangedFuture

A Future that completes with the signal’s current value on the next mutation.

SignalMap

A lightweight read-only projection of a Signal.

Functions

batch

Run f in a batch context.

in_batch

Return true if currently inside a batch context.
