C/C++ binding for Rust AMQP Worker

Based on rsamqpworker.

Build

To build the rust application bash cargo build

To build the provided worker example bash gcc -c -Wall -Werror -fpic worker.cpp gcc -shared -o libworker.so worker.o

Test

To run the unit tests, you must build the provided worker example (see the Build section above). bash cargo test

Usage

This worker uses Rust FFI to load a C/C++ Shared Object library, and to execute it. The C/C++ worker must implement some functions to be correctly bound:

• char* get_name(): to retrieve the worker name
• char* get_short_description(): to retrieve a short description of the worker
• char* get_description(): to describe the worker purpose
• char* get_version(): to retrieve the worker version
• unsigned int get_parameters_size(): to return the number of parameter, before calling...
• void get_parameters(Parameter*): to fill the allocated pointer with the worker parameters
• int process(void*, char* (*)(void*, const char*), void* ()(void*, unsigned char), void* (*)(const char*, const char*), const char**, const char***): to execute the worker process

For more details, see the provided worker.cpp example.

Set the WORKER_LIBRARY_FILE environment variable to specify the path of your C/C++ worker shared-library. Otherwise, the libworker.so file will be loaded by default.
