cpp-rotor-light

rotor-light is real-time platform-neutral, C++ actor micro-framework for embedded systems with supervising capabilities.

rotor-light is built with the concurrency in the mind, i.e. independent entities (actors) interact each other via messages.

rotor-light is adoption of rotor framework for embedded systems. The framework has no platform-dependent code, so, it can, however, be used as is on host system, if you cautiously care about thread-safety.

features

• erlang-like hierarchical supervisors

• asynchronous messaging with priorities

• plaform-agnostic code (including timers)

• C++17

• no thread-safety

• no allocations, no exceptions, no RTTI

• non-intrusiveness

• compile-time actor hierarchies
