I am not sure if we want to list the all possible exception here, but at least indent is needed as below.

I agree that introduces some maintenance hazard keeping doc and implementation in sync, but it could be practical to have it there.
I'd also be fine with just a hint at some general throw behavior here.
So I'd leave it up to any reviewer as I am not too familiar with the style use throughout the rest of the codebase.

@gDorndorf Thanks for PR and attempt to make our Rosbag2 better.
However, in this particular case documenting about possible throwing exceptions is not trivial. Because this is an upper rosbag2_cpp layer API which is calling storage plugin API inside.
Each storage plugin may throw or not and what type of exceptions it throws and in what cases are implementation details for concrete storage plugin.
What we can do is make some notes that certain functions may throw if the underlying rosbag2_storage plugin API also throws.
Update: we can be more specific and refer to the concrete storage_plugin API interface.

Possibly a better API would be a no-throw |
