serde_derive 0.8.7 on Rust Cargo

Add a forward_to_deserialize! macro to simplify JSON-like Deserializer implementations that want to ignore type hints given by Deserialize (#525)

impl Deserializer for MyDeserializer {
    fn deserialize<V>(&mut self, visitor: V) -> Result<V::Value, Self::Error>
        where V: Visitor
    {
        /* ... */
    }

    forward_to_deserialize! {
        bool usize u8 u16 u32 u64 isize i8 i16 i32 i64 f32 f64 char str string
        unit option seq seq_fixed_size bytes map unit_struct newtype_struct
        tuple_struct struct struct_field tuple enum ignored_any
    }
}

Add constructors for the Bytes and ByteBuf helpers (#520)
Allow MapDeserializer to be deserialized as a sequence of pairs instead of a map (#527)
Fix warnings in generated code for a non-unit struct with no fields (#536)
Minor cleanup of generated serialization code (#538)
