Interface of the thespis actor model.

The interface of the thespis actor model (contains only traits). This defines the expected behavior for Addresses that can send to Actors, as well as the [Handler] trait and the [Message] trait.

There used to be a Mailbox trait, but it turns out that the mailbox is not depended on by any of the other components, so it's iplementation can be freely changed without requiring an interface.

The purpose for the split between interface and implementation is 2-fold:

  1. Libraries can expose an actor based interface without having to depend on an implementation. Consumers can then choose any implementation they want and everything will remain inter-operable.
  2. Each component can be individually replaced and composed if you need a different behavior then the reference implementation.

The reference implementation can be found in the thespis_impl crate.

To get started with thespis, please check out the guide level documentation.

This crate has few dependencies. Cargo will automatically handle it's dependencies for you. Check Cargo.yml for the list of dependencies.

There is one optional feature, derive, enabled by default which adds proc macros for deriving the Message trait as well as removing some boilerplate when implementing Handler.


This crate does not use unsafe, but it's dependencies do.


Please refer to the thespis_impl crate to see examples of usage.


API documentation can be found on docs.rs.


Please check out the contribution guidelines.


As this crate only provides traits, there aren't any tests. You can check the thespis_impl crate for the tests.
