Make Script::fmt_asm a static method and add Script::str_asm
This makes it convenient to print/construct the script assembly on
byte slices withoout having to clone them to copy them to create a
Script struct.

transaction: add a method to err on non-standard types to SigHashType
Right now, any sighash type could be parsed without error, which matches
consensus rules. However most of them would be invalid by standardness,
so it's a bit footgun-y (even more so for pre-signed transactions
protocols for which standardness is critical).

This adds `from_u32_standard()`, which takes care to error if we are
passed an invalid-by-current-policy-rules SIGHASH type.

Super nit, but a hashtype is not specific to a transaction but a
signature.

Return BlockHash from BlockHeader::validate_pow
Validating a block's proof-of-work involves computing the block hash.
Returning it from BlockHeader::validate_pow avoids having callers
recompute the block hash if it is needed.

Change the signature of consensus_encode to return io::Error's
This is instead of encode::Errors because the encoders should
not be allowed to return errors that don't originate in the writer
they are writing into.

This is a part of the method definition that has been relied upon for a
while already.

Max Giraldo 21b2f929c5 refactor(blockdata/transaction): use nested paths
Instead of using a wildcard path for the `hash_types` module,
be explicit about what types we're using by using nested paths.

There are many benefits to this, including not polluting the namespace
and clearly demarcating the types' location.

Matt Corallo acb43af981 Drop byteorder dependency
Taking an external dependency just to convert ints to byte arrays
is somewhat of a waste, especially when Rust isn't very aggressive
about doing cross-crate LTO.

Note that the latest LLVM pattern-matches this, and while I haven't
tested it, that should mean this means no loss of optimization.

Andrew Poelstra a181a523c6 remove special case for 0-input 0-output transaction deserialization
This creates two ways to encode an empty transaction; we should use only the
Segwit-enabled one because that's what we do for 0-input non-0-output transactions.

Rename `TxOutRef` to `OutPoint` and use it in `TxIn`.
2018-08-20 18:18:00 +00:00
Jean Pierre Dudey 32631e44ad Rename `TxOutRef` to `OutPoint` and use it in `TxIn`.
Previously this structure was unused, it's now being used by the `TxIn`
structure to simplify the code a little bit and avoid confusions. Also
the rust-lightning source code has an `OutPoint` similar to this one
but with the `vout` index as an `u16` to avoid unsafe conversions.

I've added to new methods to `OutPoint`:

- `null`: Creates a new "null" `OutPoint`.
- `is_null`: Checks if the given `OutPoint` is null.

Jean Pierre Dudey 1b4aba1d80 Update serde to 1.0 and strason to 0.4
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.

Savil Srivastava 933dcaeb82 [code hygiene] remove deprecated rustc-serialize
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.

Matt Corallo a33f00621b Move witness inside of TxIn.
This is a rather large breaking API change, but is significantly
more sensible. In the "do not allow internal representation to
represent an invalid state" category, this ensures that witness
cannot have an length other than the number of inputs. Further,
it reduces vec propagation, which may help performance in some
cases by reducing allocs. Fianlly, this just makes more sense (tm).
Witness are a per-input field like the scriptSig, placing them
outside of the TxIn is just where they are serialized, not where
they logically belong.
