Henry de Valence 7d0a3debb6 chain: ensure impl Deserialize for Amount validates data. 
This uses serde's try_from attribute to run deserialized values through the
TryFrom impl.  Also adds a test to make sure that validation actually does
happen.

Henry de Valence 4aa00ad216 Align crate versions and user-agent with NU numbers. 
We had a brief discussion on discord and it seemed like we had consensus on the
following versioning policy:

* zebrad: match major version to NU version, so we will start by releasing
  zebrad 3.0.0;

* zebra-* libraries: start by matching zebrad's version, then increment major
  versions of each library as we need to make breaking changes (potentially
  faster than the zebrad version, always respecting semver but making no
  guarantees about the longevity of major releases).

This commit sets all of the crate versions to 3.0.0-alpha.0 -- the -alpha.0
marks it as a prerelease not subject to perfect adherence to compatibility
guarantees.

Henry de Valence 60f3f35d89 Refine Ed25519 byte arrays to ed25519-zebra types. 2020-01-24 16:43:31 -05:00
Henry de Valence 53cae4647e Make invalid ShieldedData unrepresentable. 
ShieldedData objects must have at least one spend or output; using Either
ensures that at least one must be present.  This is similar to the
JoinSplitData case, but slightly more complicated: rather than enforcing that
one list has at least one element (which can be done as `(first, rest)`), here
we need to use Either.   This has the downside that it is possible to construct
multiple equivalent internal representations (choosing whether a spend or
output goes in the `first` slot), but this easily fixed with a custom PartialEq
implementation.
