Because features and dependencies share the same namespace, and we want
to pass down the optional dependence on serde to bitcoin_hashes, we need
to rename the feature to something other than serde. Right now only
features can be passed down to dependencies.
Note that we could have also renamed the dependency to something like
serde-dep and kept the same feature name, however, dependency renaming
has only been available since cargo 0.27.0
Features that represent optional dependencies have been prefixed with
'use-'. The travis file has also been modified to conform to this
change.
The `serde_struct_impl!` macro has been modified to be compatible
with the serde 1.0 crate, we use this macro and not the `serde_derive`
crate because the latter doesn't support Rust 1.14.0 which is shipped
on Debian stable and we should remain compatible with it.
Two new features were added:
- "serde": enables serialization/deserialization for common types, it pulls
the serde 1.0 dependency.
- "serde-decimal": enables serialization/deserialization for `UDecimal`/`Decimal`,
this pulls the strason 0.4 depdendency and the serde 1.0 dependency.

Also I've updated the feature name on the README.md, and fixed a typo in
src/blockdata/script.rs

Addresses #96.
Turns out it was being used for hex encoding/decoding, so replaced that with the `hex` crate.
i chose to import the `decode` method as:
```
use hex::decode as hex_decode
```
so that it is clear to the reader what is being decoded when it is called. "decode" is such a generic sounding function name that it would get confusing otherwise.
This is needed to for a sane BIP143 implementation. Should be exactly equivalent to
serializing data into a vector then hashing that vector for all types.
Needed for applications where the tweak and the secret key material are on different
devices (and the one with the secret material does not want to know how to compute
the tweak itself).
This code was unmaintained, is unlikely to work on the majority of systems
(since it holds the whole utxoset in RAM, and not in a terribly efficient
manner), and has a dependency on `eventual` which has been broken for a
long time.
The library no longer compiles on nightly because of this, and without any
known usecases for `UtxoSet`, nor good ability to test it, I'm simply
removing the code.
I recommend anyone who cares about this extracts the code from the previous
commit and creates a new crate. It should be more featureful anyway, e.g.
support a backing store.
Rather than having methods taking &mut self, have them consume self
and return another Builder, so that methods can be chained.
Bump major version number.
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>>
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.
