## serde-big-array
[](https://docs.rs/crate/serde-big-array)
[](https://crates.io/crates/serde-big-array)
[](https://deps.rs/repo/github/est31/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](https://github.com/serde-rs/serde/issues/1937).
Bases on [this](https://github.com/serde-rs/serde/issues/631#issuecomment-322677033) snippet.
```Rust
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[..]);
}
```
