rill-adrift

rill-adrift is the umbrella crate for the Rill ecosystem — a modular signal processing framework for Rust.

One dependency brings in the entire ecosystem:

[dependencies]
rill-adrift = "0.6.0-M2"

#![allow(unused)]
fn main() {
use rill_adrift::prelude::*;
use rill_adrift::rill_core_dsp::generators::SineOscillator;
}

What is Rill?

Rill is not a monolith. It is a collection of specialized crates, each solving one problem well:

Layer	Crates
Core	`rill-core` — traits, math, buffers, queues, time, macros
Actor	`rill-core-actor` — lock-free actor model (ActorRef, ActorSystem)
DSP	`rill-core-dsp` — algorithms, filters, generators, delay, vector ops
Graph	`rill-graph` — static DAG signal graph, `GraphBuilder`; `build_ir()` produces `GraphIr` compiled by `rill-lang` into a `CompiledGraphEngine`
Effects	`rill-digital-filters`, `rill-digital-effects`, `rill-router`
FFT	`rill-fft` — radix-2 FFT, frequency-domain convolution, spectral effects
Automation	`rill-patchbay` — LFO, envelopes, sensors, servos, mappings
Language	`rill-lang` — Faust-style functional signal DSL, compiles to `Algorithm<T>` or `MultichannelAlgorithm<T>`, or to `CompiledGraphEngine` for whole-graph compilation
Analog	`rill-core-model`, `rill-analog-filters`, `rill-analog-effects` — WDF circuit modeling
I/O	`rill-io` — ALSA, PortAudio, PipeWire, JACK backends (pure I/O, no engine)
Network	`rill-osc` — OSC server and networking; powers `rill-patchbay` OSC sensors for graph control
Monitoring	`rill-telemetry` — probes, collectors
Sampler	`rill-sampler` — sample playback, time-series reader, WAV loading
Lo-Fi	`rill-lofi` — vintage DAC, tape effects, chip emulation (NES, AY-3-8910, Akai S900)
Umbrella	`rill-adrift` — re-exports all workspace crates
Devtools	`rill-analyzer` — interactive gdb-style debugger for signal graph inspection

Domain-Agnostic

Only rill-io is tied to audio hardware. The rest work anywhere — IoT, embedded, robotics, control systems, signal processing.

The foundation (rill-core) provides lock-free queues, no_std-compatible math traits, and real-time safe abstractions that apply to any signal domain.
