Borsh in Rust  

borsh-rs is Rust implementation of the Borsh binary serialization format.

Borsh stands for Binary Object Representation Serializer for Hashing. It is meant to be used in security-critical projects as it prioritizes consistency, safety, speed, and comes with a strict specification.

Example

use borsh::{BorshSerialize, BorshDeserialize, from_slice, to_vec};

#[derive(BorshSerialize, BorshDeserialize, PartialEq, Debug)]
struct A {
    x: u64,
    y: String,
}

#[test]
fn test_simple_struct() {
    let a = A {
        x: 3301,
        y: "liber primus".to_string(),
    };
    let encoded_a = to_vec(&a).unwrap();
    let decoded_a = from_slice::<A>(&encoded_a).unwrap();
    assert_eq!(a, decoded_a);
}

Testing

Integration tests should generally be preferred to unit ones. Root module of integration tests of borsh crate is linked here.

Releasing

The versions of all public crates in this repository are collectively managed by a single version in the workspace manifest.

So, to publish a new version of all the crates, you can do so by simply bumping that to the next "patch" version and submit a PR.

We have CI Infrastructure put in place to automate the process of publishing all crates once a version change has merged into master.

However, before you release, make sure the CHANGELOG is up to date and that the [Unreleased] section is present but empty.
