## What it is
Kanal is a high-performance Rust channel library implementing CSP-style message passing with both synchronous and asynchronous APIs. It supports mpmc, mpsc, and oneshot channels and unifies communication between sync and async code.

## Use cases
- pass messages between threads in Rust
- communicate between sync and async Rust code
- fast mpmc channel for concurrent workers
- replace std::sync::mpsc for better performance
- oneshot channel for single-value handoff
- tokio-compatible channel with sync API

## When to choose
- you need top channel throughput in Rust
- your code mixes sync threads and async runtimes
- you need mpmc semantics beyond std mpsc

## When to avoid
- you only need a simple channel and std::sync::mpsc suffices
- you need broadcast channels or complex stream combinators

## Facets
- artifact type: library
- maturity: active
- function: concurrency, message-queue
- domain: developer-tools, performance
- platform: rust, cross-platform
- tags: mpmc, mpsc, oneshot, csp, sync-async, message-passing, algorithms
