Each channel now remembers an OwnedChanTarget.
Each circuit now remembers a vector of OwnedChanTarget to represent
the path that it was constructed for.
Part of #415.
Instead of requiring a `Box<dyn Isolation>`, it now takes either a
`Box<dyn Isolation>`, or an arbitrary `T` that implements
`Isolation`.
This API still allows the user to pass in a `Box<dyn Isolation>` if
that's what they have, but it doesn't require them to Box the
isolation on their own.
Part of #414.
Now we use NetParams. That implies making its constructor public,
which I think it fine.
This is related to #413 but is far from completing that ticket.
This handwritten conversion function omitted a field. There was
nothing to spot this mistake.
IMO this shows why these particular types ought not to use builders,
but instead, should cause API breaks when things change.
Adding this line here to explicitly fix the bug, although we are about
to abolish this function completely almost right away.
This has the different syntax for builder field attributes than what I
originally proposed in my MR, and which therefore is in the pinned
branch.
My upstream MR for the field attributes feature was morged:
https://github.com/colin-kiegel/rust-derive-builder/issues/239
Every time we want a microdescriptor, we know the index of that
microdesc's corresponding routerstatus within the consensus.
Therefore, we can use that index to store `Arc<Microdesc>`s in a
dense array, and not have to use a HashSet here at all.
We were using a hashtable to keep track of missing microdescriptor
digests. But this information is redundant with the NetDir state,
and there's now no longer any performance benefit to keeping a
separate copy.
Part of #386.
We previously kept missing-MD entries and present-MD entries all in
the same HashSet, which resulted in using more slack space than we
need. Now we use separate tables, so we can drop missing-MD
entries as we move forward.
Also, when constructing a NetDir, set its hash tables to their final
capacities.
This also lets us simplify some of our missing-md-listing code a
lot.
