The trait was introduced while introducing generic scalars, but is not
actually required or useful. It's functionality is fully covered by
methods on the `ScalarValue` trait.
It also forced a lof of for<'a> ScalarRefValue bounds all over the code,
complicating signatures a lot.
It is completely removed now.
This commit implements a newtype style custom derive
for scalars via `#[derive(GraphQLScalarValue)]`, which now
supports both deriving a base enum scalar type and newtypes.
For newtypes, the `#[graphql(transparent)]` attribute is
required.
This commit:
* implements the derive
* adds integration tests
* updates the book
Currently, custom derives inside the main juniper crate are supported by
an ugly hack using the __juniper_use_everything macro.
This commit adds new custom derive variants that are for
main juniper crate internal use only (GraphQL{Enum,InputObject}Internal.
All custom derives inside the juniper crate are refactored to use the
new '*Internal' derives.
This allows us to
* remove the use_everything macro,
* simplify the generated code for custom derives
* support the Rust 2018 edition
