+# serde\_bytes [![Build Status](https://img.shields.io/github/actions/workflow/status/serde-rs/bytes/ci.yml?branch=master)](https://github.com/serde-rs/bytes/actions?query=branch%3Amaster) [![Latest Version](https://img.shields.io/crates/v/serde_bytes.svg)](https://crates.io/crates/serde_bytes)
+
+Wrapper types to enable optimized handling of `&[u8]` and `Vec<u8>`.
+
+```toml
+[dependencies]
+serde_bytes = "0.11"
+```
+
+## Explanation
+
+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`.
+
+Additionally this crate supports the Serde `with` attribute to enable efficient
+handling of `&[u8]` and `Vec<u8>` in structs without needing a wrapper type.
+
+## Example
+
+```rust
+use serde::{Deserialize, Serialize};
+
+#[derive(Deserialize, Serialize)]
+struct Efficient<'a> {
+ #[serde(with = "serde_bytes")]
+ bytes: &'a [u8],
+
+ #[serde(with = "serde_bytes")]
+ byte_buf: Vec<u8>,
+}
+```

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