Adding `serde_big_array` library as a dependency

Run this command in a terminal, in your project's directory:

cargo add serde-big-array

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

serde-big-array = "0.5.1"

The serde_big_array library will be automatically available globally. Read the serde_big_array library documentation.

Readme

serde-big-array

Big array helper for serde. The purpose of this crate is to make (de-)serializing arrays of sizes > 32 easy. This solution is needed until serde adopts const generics support.

Bases on this snippet.

extern crate serde;
#[macro_use]
extern crate serde_derive;
extern crate serde_json;
#[macro_use]
extern crate serde_big_array;

use serde_big_array::BigArray;

#[derive(Serialize, Deserialize)]
struct S {
    #[serde(with = "BigArray")]
    arr: [u8; 64],
}

#[test]
fn test() {
    let s = S { arr: [1; 64] };
    let j = serde_json::to_string(&s).unwrap();
    let s_back = serde_json::from_str::<S>(&j).unwrap();
    assert!(&s.arr[..] == &s_back.arr[..]);
}
