kandi X-RAY | iceoryx Summary
Great that you've made it to this little Eclipse project! Let's get you started by providing a quick background tour, introducing the project scope and all you need for installation and a first running example. So first off: What is iceoryx?. iceoryx is an inter-process-communication (IPC) middleware for various operating systems (currently we support Linux, MacOS, QNX and Windows 10). It has its origins in the automotive industry, where large amounts of data have to be transferred between different processes when it comes to driver assistance or automated driving systems. However, the efficient communication mechanisms can also be applied to a wider range of use cases, e.g. in the field of robotics or game development. iceoryx uses a true zero-copy, shared memory approach that allows to transfer data from publishers to subscribers without a single copy. This ensures data transmissions with constant latency, regardless of the size of the payload. For more information have a look at the 1000 words iceoryx introduction. You're right, middleware is a cluttered term and can somehow be all or nothing, so let's talk about the goals and non-goals of iceoryx.

QUESTION
I have a struct with a method called call
which has a const overload. The one and only argument is a std::function
which either takes a int reference or a const int reference, depending on the overload.
The genericCall
method does exactly the same thing but uses a template parameter instead of a std::function
as type.
ANSWER
Answered 2022-Apr-08 at 13:25The problem is that generic lambdas (auto param) are equivalent to a callable object whose operator()
is templated. This means that the actual type of the lambda argument is not contained in the lambda, and only deduced when the lambda is invoked.
However in your case, by having specific std::function arguments, you force a conversion to a concrete type before the lambda is invoked, so there is no way to deduce the auto type from anything. There is no SFINAE in a non-template context.
With no specific argument type, both your call
are valid overloads. Actually any std::function that can match an [](auto&)
is valid. Now the only rule is probably that the most cv-qualified overload wins. You can try with a volatile float&
and you will see it will still choose that. Once it choose this overload, the compilation will fail when trying to invoke.

Install iceoryx
If you want to avoid installing anything on your host machine but you have Docker installed, it is possible to use it to build and run iceoryx applications. Please see the dedicated README.md for information on how to do this.
