Integration test is working with the latest release of ros2 iron, but the docker images are not updated yet. |
Could you merge the latest main into the base branch also rebase/update this branch? |

This is a preview of the work in removing exceptions.
Inspired from rust,
Result<T>
is the alternative to exceptions. Internally it usesstd::variant
to store either the result or astd::exception
.[[nodiscard]]
should almost always be used when returningResult<T>
. We don't have custom lint rules so it will have to be checked manually.Result<void>
is a special case that usingstd::optional
instead.Result<T&>
does not work becausestd::variant
cannot contain references.Result<T>
for all reference types and store a pointer internally instead.
