Based on the original work by Justin Moon.
*MSRV unchanged from 1.29.0.*
When `std` is off, `no-std` must be on, and we use the [`alloc`](https://doc.rust-lang.org/alloc/) and core2 crates. The `alloc` crate requires the user define a global allocator.
* Import from `core` and `alloc` instead of `std`
* `alloc` only used if `no-std` is on
* Create `std` feature
* Create `no-std` feature which adds a core2 dependency to polyfill `std::io` features. This is an experimental feature and should be
used with caution.
* CI runs tests `no-std`
* MSRV for `no-std` is 1.51 or so
- 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
- Separate serialize::Error and network::Error from util::Error
- Remove unneeded propagate_err and consume_err
- Change fuzzing code to ignore Err type
This is a massive simplification, fixes a couple endianness bugs (though
not all of them I don't think), should give a speedup, gets rid of the
`serialize_iter` crap.
