The protocol has a bug where a 0u8 is pushed at the end of each
block header on the wire in headers messages. WHy this bug came
about is unrealted and shouldn't impact API design.
- Move network::encodable::* to consensus::encode::*
- Rename Consensus{En,De}codable to {En,De}codable (now under
consensus::encode)
- Move network::serialize::Error to consensus::encode::Error
- Remove Raw{En,De}coder, implement {En,De}coder for T: {Write,Read}
instead
- Move network::serialize::Simple{En,De}coder to
consensus::encode::{En,De}coder
- Rename util::Error::Serialize to util::Error::Encode
- Modify comments to refer to new names
- Modify files to refer to new names
- Expose {En,De}cod{able,er}, {de,}serialize, Params
- Do not return Result for serialize{,_hex} as serializing to a Vec
should never fail
- Add serialize::Error::ParseFailed(&'static str) variant for
serialization errors without context
- Add appropriate variants to replace network::Error::Detail for
serialization error with context
- Remove error method from SimpleDecoders
- Separate serialize::Error and network::Error from util::Error
- Remove unneeded propagate_err and consume_err
- Change fuzzing code to ignore Err type
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.
A fixed buffer of 12 bytes was unsafely copied from the bytes of a
string - if the string was shorter than that, memory from outside would
leak into the packet.
Replace the unsafe copy by a safe loop. Also add a panic if
an attempt is made to use a command string longer than 12 bytes.
