Derive Macro DeserializeView 

#[derive(DeserializeView)]
{
    // Attributes available to this derive:
    #[pack_io]
}

Available on crate feature derive only.

Derive pack_io::DeserializeView for a struct (zero-copy decode).

The struct MUST have exactly one lifetime parameter — used as the borrow of the underlying input buffer. Field types must implement pack_io::DeserializeView<'that_lifetime>. The built-in impls for primitives, &'a str, &'a [u8], and the standard Option / Result / tuple / array types cover the common cases.

Enum support and multi-lifetime structs are planned for a later minor release.
