Improving `units::Duration`

[elBoberido]

Brief feature description

The units::Duration class could have same additional features and improvements.

Detailed information

• rename the creation methods like milliseconds to fromMilliseconds
  • some getter methods should then be renamed, e.g. milliSeconds -> milliseconds or toMilliseconds
  • no final decision, please ask before starting with this
• conversion to/from all chrono types
• operator+=, operator-= and operator*= Iox #190 fixed point types for duration internal representation #501 (comment)
• abstractions for TimePoint for monotonic and system clock Iox #190 fixed point types for duration internal representation #501 (comment)
  • needs to be discussed and maybe another issue should be used for this

Could work on refactoring method names in units::Duration(first one), if it's still wanted.

@enkeyz It is still wanted and we would very much appreciate it!

I would assign the issue to you and if you run into troubles or other issues just contact us via https://gitter.im/eclipse/iceoryx

[elBoberido]

@enkeyz sure, go ahead. If it's not too late, please rename the getter methods with a to prefix, so toDays, toNanoseconds. This makes it's less ambiguous than just nonoseconds which could also mean just to nanoseconds part of the duration.

Already finished with it, just one question: how to correctly run the "run_all_tests.sh" from tools folder?

@enkeyz nice!

Getting error message: "make: *** No rule to make target 'all_tests'. Stop."

I would recommend to use the iceoryx_meta approach for developing. Here you can compile and run the tests with the following commands:

cd iceoryx
cmake -Bbuild -Hiceoryx_meta -DBUILD_TEST=ON
cd build
make
make all_tests # executes all unit- and integrationtests
