This just clones the fields. It is not clear to me why it was
written this way in be86df631d
Remove anyhow dependency from tor-retry, and rename it to retry-error
Previously, I think, RetryError wasn't Clone.
When I wrote this, I arranged to skip dumping the field `pending`.
This must have been because I thought that either
(a) PendingEntry couldn't `#[derive(Debug)]` (but it can)
and/or
(b) Some of the fields of PendingEntry ought not to be dumped because
they might contain (eg) packet data. But I think they don't: there's
just the spec, and the Result which is (basically) a Circ.
I tried preseving something closer to the original using educe, but
educe gets somehow tangled up with the generics, and the result fails
to compile. I haven't investigated this further.
This makes using the `PreferredRuntime` the first-class option inside
`arti-client`, freeing users who don't want to think about runtimes from
having to do so.
`TorClient::create_unbootstrapped` and `builder` now automatically
use this runtime, leaving only `builder_custom` for users who wish to
manually specify a runtime.
This lets us clean up the docs a lot: mentions of using custom runtimes
are now relegated to nearer the end of the crate-level documentation,
and we mostly just link to `tor_rtcompat`'s docs to explain more there.
Instead, we take some more time to explain how you use the builder API
to create clients synchronously.
Other doc cleanups included getting rid of the explanation of `TorAddr`
in the main crate-level doc; this is already well-documented elsewhere,
and is something users should discover organically later.
fixes arti#326
Add tls_conn field to ArtiHttpConnector (and argument to constructor).
Introduce MaybeHttpsStream and use it in ArtiHttpConnection.
Have the example program pass the native TLS connector.
Currently the TLS connector and the HTTPS variant are not used, but
this commit is very noisy and fomrulaic, so I have split out the code
to use them into a separate commit for easier preparation and review.
arti-hyper wants to be able to have a kind for TLS failure.
Given that arti-hyper is above arti-client, this shows that callers
above arti-client might need to invent kinds for their own errors.
Possibly this means we need other Other errors for other locations.
If we have pluggable components we might even want OtherTorError.
