serde-BOLT
==============
[](https://crates.io/crates/serde_bolt)
[](https://docs.rs/serde_bolt/)
[](https://github.com/rust-secure-code/safety-dance/)
An incomplete implementation of the Lightning BOLT message serialization format. Compatible with rust-bitcoin `Encodable` and `Decodable` traits.
Unlike rust-bitcoin, the default is big-endian encoding and u16/u32 for length fields for the following types:
- Octets (u16 length field)
- Array (u16 length field)
- LargeOctets (u32 length field)
- IgnoredLargeOctets (u32 length field)
`Option` is implemented as a single byte, with `None` as `0x00` and `Some` as `0x01` followed by the value.
Domain-specific types are not implemented. You can just use `Array<u8>` or `[u8; nnn]` or a wrapped version thereof.
Structs and tuples are considered transparent - they are not delimited in the stream.

```rust
use hex::{encode, decode};
extern crate alloc;
use serde_bolt::{to_vec, from_vec, bitcoin::consensus::{Encodable, Decodable}, Array};
use bitcoin_consensus_derive::{Encodable, Decodable};
#[derive(Encodable, Decodable, PartialEq, Debug)]
struct Thing([u8; 3]);
#[derive(Encodable, Decodable, Debug)]
struct Test {
x: bool,
a: u32,
b: u8,
c: Option<u16>,
d: Option<u16>,
e: Array<u8>,
/// Sub-structs are transparent
f: Thing
}
#[test]
fn test_simple() {
let test = Test {
x: true,
a: 65538, b:160, c: None, d: Some(3),
e: vec![0x33, 0x44].into(),
f: Thing([0x55, 0x66, 0x77])
};
let result = to_vec(&test).unwrap();
assert_eq!("0100010002a00001000300023344556677", encode(&result));
let decoded: Test = from_vec(&mut result.clone()).unwrap();
assert_eq!(test.a, decoded.a);
assert_eq!(test.f, decoded.f);
}
```
