For me a number of tests failed, I'm not sure why: https://gist.github.com/sunshowers/5ad72397fe70205bbb27cae534d65443#file-gistfile0-txt-L4551-L4685 But those tests also failed for me on main. (This is with |

I have a feeling this isn't quite correct. I think it might generate paths that are too long. Going to try looking at it later this week. |

i'm not familiar with the OsString arbitrary impl but I'm wondering if it can generate a string with a delimiter in it. will pull this locally and mess around more. otherwise this looks good.

OsString strategy does indeed generate strings with the delimiter.

I think that's okay, the number of delimiters is not a hard and fast rule here.
I'm more concerned about the number of components being too large by default.
I'm wondering if we should define a PathParameters struct with a custom default value for the number of delimiters.

I did notice that quite a few components were getting generated. I think a PathParameters struct with a default number and ensuring the output has that number (which may involve trimming any excess generated) could make sense. I think it'd be an un-intuitive if a user asks for n segments and we give them n + m.

That makes sense. You're welcome to work on it, or I'll get around to it at some point later this week (speaking at RustConf in 3 days 😅)

@matthew-russo OK, done. Let me know if this makes sense.

Sorry work and personal life have kept me quite busy so I missed your last message. Thanks for getting back to this and congrats on the talk!

non-blocking: it is actually pub(?) not sure if this just means it isn't intended to be publicly used or if this is residual from previous iterations.

I meant that even though it is pub, it is not exported as an API so that backwards compatibility is maintained. Any suggestions for better phrasing?

I don't think its a huge deal either way. I would probably just say something like:
