Can this be a zero? I think with the "zero index == null" convention we've been trying to avoid having to use -1 as a special value.

noAttrUnit is just an conversion internal helper and will not be seen in the resulting OTel profiles output. As every positive value can indicate a unit, i needed something to indicate that no unit is set for this attribute.

Thank you for this work. A nit on the test code, and a few notes on the TODOs in the code. Do you want to address the TODOs in this PR or deal with them in other PRs? |

Not a blocker for this PR, but if we are willing to add a pprof exporter, we could consider moving this to a pprof translator package

maybe @MovieStoreGuy or @atoulme can answer the question on why they chose to create receiver/pprofreceiver over a translator package.

@atoulme the TODOs were a reminder for myself to discuss the topic of the id fields from pprof with the Profiling SIG. As this is not relevant for this PR, I have removed them with 00333f2. |
