Only count timeouts when we've seen net activity.

2021-12-20T20:34:17Z

This closes arti#256. It makes our behavior match Tor's more closely, though it has a simpler implementation than Tor. I think that the extra complexity in Tor's logic is because we used to record timeouts in the histogram as well as in the success/failure log.

fix nightly clippy errors

Use a safer histogram rebuild algorithm.

Our old algorithm could, on some inputs, exhaust RAM. That's not great, since we try to be robust againt corruption to the state file.

Change an XXX in pareto.rs: a ticket is now open.

Use a panic-free function to multiply timeouts.

2021-12-06T21:00:17Z

Previously we used Duration::mul_f64, which panics if its output is out-of-range. That shouldn't actually be possible for the values we're giving it, but probably it's better to just multiply in a safe way. This resolves a couple of XXXXs and therefore relates to #231.

add semicolons if nothing returned

Add #[serde(flatten)] HashMap fields to serializable objects

2021-10-27T12:31:52Z

As per arti#175, we'd like to be able to handle newer Arti versions storing additional state in the persisted state files, without dropping this data on the floor when we write out changes to these files. Use the #[serde(flatten)] mechanism to achieve this, by adding catch-all HashMap fields to all structs that are at risk of this happening to them.

Add a timeout estimator to take estimates from another process.

2021-10-20T16:41:59Z

Allow type of timeout estimator to change at runtime.

2021-10-20T16:06:58Z

This is a big change, but it does simplify the type of Builder a little, and isolates locking across different (potential) timeout estimator types.

enable checked_conversions lint.
