Wrapper types to enable optimized handling of &[u8] and Vec<u8>.
[dependencies]
serde_bytes = "0.11"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.
