Conduit overview

Quiet, fast, annotation-driven events.

Conduit is a tiny event bus for Java with a simple API and a focus on predictable dispatch. It keeps the surface area small: register listeners, post events, and keep moving.

What is Conduit?

Conduit is a lightweight event bus built around annotations. It supports synchronous dispatch by default, optional async dispatch with an Executor, cancellable events, and deterministic ordering.

• Zero external dependencies.
• Supports priorities, once-only handlers, and subtype dispatch.
• Weak listener references to avoid accidental leaks.
• Dead-event diagnostics when nothing is listening.
