# serde\_bytes [](https://travis-ci.org/serde-rs/bytes) [](https://crates.io/crates/serde_bytes)
|
|
|
|
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_bytes::Bytes` and `Vec<u8>` by wrapping it
|
|
in `serde_bytes::ByteBuf`.
|
|
|
|
This crate supports the Serde `with` attribute to enable efficient handling
|
|
of `&[u8]` and `Vec<u8>` in structs without needing a wrapper type.
|
|
|
|
```rust
|
|
#[macro_use]
|
|
extern crate serde_derive;
|
|
|
|
extern crate serde;
|
|
extern crate serde_bytes;
|
|
|
|
#[derive(Serialize)]
|
|
struct Efficient<'a> {
|
|
#[serde(with = "serde_bytes")]
|
|
bytes: &'a [u8],
|
|
|
|
#[serde(with = "serde_bytes")]
|
|
byte_buf: Vec<u8>,
|
|
}
|
|
|
|
#[derive(Serialize, Deserialize)]
|
|
struct Packet {
|
|
#[serde(with = "serde_bytes")]
|
|
payload: Vec<u8>,
|
|
}
|
|
```
