serde-human-bytes

A fork of serde_bytes that serialize bytes to hex string when the format is human readable.

[dependencies]
serde-human-bytes = "0.1"

Example

use serde::{Deserialize, Serialize};

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

    #[serde(with = "serde_human_bytes")]
    byte_buf: Vec<u8>,
}

lib.rs:

Wrapper types to enable optimized handling of &[u8] and Vec<u8>.

Without specialization, Rust forces Serde to treat &[u8] just like any other slice and Vec<u8> just like any other vector. In reality this particular slice and vector 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] by wrapping it in serde_human_bytes::Bytes and Vec<u8> by wrapping it in serde_human_bytes::ByteBuf.

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

use serde::{Deserialize, Serialize};

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

    #[serde(with = "serde_human_bytes")]
    byte_buf: Vec<u8>,

    #[serde(with = "serde_human_bytes")]
    byte_array: [u8; 314],
