Also:
- Move generator functions to `alice` and `bob` modules. This makes
using `tracing` a lot easier, since the context of the file name let's
us differentiate between Alice's and Bob's generator logs more
clearly.
- Accept 0 confirmations when watching for the Monero lock
transaction. This should eventually be configured by the application,
but in the tests it's making things unexpectedly slower.
The database is now bound to a type eg. alice::State or bob::State.
The caller cannot expect to retrieve a type that is different to
the type that was stored.
ECDSAfun's serialisation implementation was already imported
making the custom implementation redundant
Remove remnants of stale comment
Remove redundant conversion
Rename params to be consistent
NOTE: This implementation saves secrets to disk! It is not
secure.
The storage API allows the caller to atomically record the state
of the protocol. The user can retrieve this recorded state and
re-commence the protocol from that point. The state is recorded
using a hard coded key, causing it to overwrite the previously
recorded state. This limitation means that this recovery
mechanism should not be used in a program that simultaneously
manages the execution of multiple swaps.
An e2e test was added to show how to save, recover and resume
protocol execution. This logic could also be integrated into the
run_until functions to automate saving but was not included at
this stage as protocol execution is currently under development.
Serialisation and deserialisation was implemented on the states
to allow the to be stored using the database. Currently the
secret's are also being stored to disk but should be recovered
from a seed or wallets.
- Make it the same for Alice and Bob.
- Make it contain a wallet client instead of the `Monero` struct.
Also:
Remove `Container` from inside `Monero` struct. The caller of `new`
can simply ensure that `Container` is not dropped to keep the
container alive.
This makes the `Monero` struct easier to work with, as it just holds
the data necessary to create the different clients created during
`init`, and does not have any lifetime restrictions.
Instead of checking once to see if Monero's `TxLock` has been
published, the new trait should keep looking until the transaction has
been found.
The new trait also allows the caller to set an expected number of
confirmations on the transaction.
The implementation of the trait is currently part of test code, but it
should be similar to what we will eventually do for an application.
