serde_byte_array

Wrapper types to enable optimized handling of [u8; N]

Explanation

Without specialization, Rust forces Serde to treat [u8; N] just like any other arary In reality this particular array can often be serialized and deserialized in a more efficient, compact representation in many formats.

When working with such a format, you can opt into specialized handling of [u8; N] by wrapping it in serde_byte_array::ByteArray<N>.

Additionally this crate supports the Serde with attribute to enable efficient handling of [u8; N] and &[u8; N] in structs without needing a wrapper type.

Example

use serde::{Deserialize, Serialize};

#[derive(Deserialize, Serialize)]
struct Efficient<'a> {
    #[serde(with = "serde_byte_array")]
    bytes: [u8; 3],

    #[serde(with = "serde_byte_array", borrow)]
    bytes_ref: &'a [u8; 3],
}
