1//! # Rill Core Prelude
2//!
3//! This module re-exports the most commonly used types and traits from rill-core.
4//! Import it with `use rill_core::prelude::*;` to get access to all essential
5//! items for working with the Rill ecosystem.
6//!
7//! ## What's included
8//!
9//! - Core traits (`AudioNode`, `Source`, `Processor`, `Sink`)
10//! - Node identification (`NodeId`, `NodeMetadata`, `NodeCategory`)
11//! - Parameter handling (`ParameterId`, `ParamValue`, `ParamType`)
12//! - Ports (`PortId`, `PortType`, `PortDirection`)
13//! - Time and clock (`ClockTick`, `ClockSource`, `SystemClock`)
14//! - Error types (`ProcessResult`, `ProcessError`, etc.)
15//! - Buffer types (`PipeBuffer`, `FanOutBuffer`, `DelayLine`, `RingBuffer`)
16//! - Atomic types (`AtomicCell`, `AtomicStats`)
17//! - Math abstractions (`Scalar`, `Transcendental`)
18//! - Constants (`DEFAULT_BLOCK_SIZE`, `MAX_SAMPLE_RATE`, etc.)
19//!
20//! ## Example
21//!
22// В rill-core/src/lib.rs - строка 151 (пример prelude)
23
24//! ## Example
25//!
26//! ```rust
27//! use rill_core::prelude::*;
28//!
29//! fn process_block<T: Transcendental, const BUF_SIZE: usize>(
30//!     source: &mut dyn Source<T, BUF_SIZE>,
31//!     processor: &mut dyn Processor<T, BUF_SIZE>,
32//!     sink: &mut dyn Sink<T, BUF_SIZE>,
33//!     clock: &ClockTick,
34//! ) -> ProcessResult<()> {
35//!     source.generate(clock, &[], &[])?;
36//!     processor.process(clock, &[], &[], &[], &[])?;
37//!     sink.consume(clock, &[], &[], &[], &[])?;
38//!     Ok(())
39//! }
