This is easy to satisfy given that the template-to-script code takes a
slice of keys. Just do &keys[..n_keys] if you have too many keys. (If
you have too few you're SOL no matter what.) This way we can catch
likely configuration errors without putting much of a burden on users
who legitimately have more keys than the template requires.
Also add a method required_keys() to Template so that users can check
how many keys they ought to have.
This is easy for downstream to add, not easy for them to remove. Plus scripts
have a pretty recognizable form and are usually obvious from context anyway.
Does not do stuff like validating the form of contracts, since this seems like
more of an application thing. Does not even distinguish a "nonce", just assumes
the contract has whatever uniqueness is needed baked in.
Breaking changes are:
opcode::All::from_u8 is now From<u8>
script::Builder::from_vec is now From<Vec<u8>>
script::Script::from_vec is now From<Vec<u8>>
There is still a lot of work to do modernizing the library, but the code
compiles cleanly with all unit tests passing now. Probably not much can
be done now until wizards-wallet is in better shape and the library is
actually in use.
Work is stalled on some other library work (to give better lifetime
requirements on `eventual::Future` and avoid some unsafety), so
committing here.
There are only three errors left in this round :)
Also all the indenting is done, so there should be no more massive
rewrite commits. Depending how invasive the lifetime-error fixes
are, I may even be able to do sanely sized commits from here on.
27 files changed, 3944 insertions(+), 3812 deletions(-) :} I've
started doing whitespace changes as well, I want everything to
be 4-space tabs from now on.
BTW after all this is done I'm gonna indent the entire codebase...
so `git blame` is gonna be totally broken anyway, hence my
capricious cadence of commits.
Will take some experimentation to see if this is what I want the API
to be, if the memory usage is acceptable, etc.
This will force a total reindex for wizards-wallet users.

Reconnecting an existing socket simply was not working; the Rust socket
did not expose any methods for reconnection, so I simply tried calling
connect() again. As near as I can tell, this was a no-op --- which makes
sense because both the sending and receiving threads had their own copy
of the Socket, and it's not clear what the synchronization behaviour
should have been.
Instead if the connection fails, we relay this information to the main
thread, wait for an acknowledgement, then simply destroy the listening
thread. The caller can then simply call `start()` again.
