These functions are from Language.GraphQL.Schema. There are actually only two generic types in GraphQL: Scalars and objects. Enum is a scalar value. According to the specification enums may be serailized to strings. And in the current implementation they used untyped strings anyway, so there is no point to have differently named functions with the same implementation as their scalar counterparts.
Haskell GraphQL
GraphQL implementation in Haskell.
This implementation is relatively low-level by design, it doesn't provide any mappings between the GraphQL types and Haskell's type system and avoids compile-time magic. It focuses on flexibility instead, so other solutions can be built on top of it.
State of the work
For now this only provides a parser and a printer for the GraphQL query
language and allows to execute queries and mutations without the schema
validation step. But the idea is to be a Haskell port of
graphql-js.
For the list of currently missing features see issues marked as "not implemented".
Documentation
API documentation is available through hackage.
You'll also find a small tutorial with some examples under docs/tutorial.
Contact
Suggestions, contributions and bug reports are welcome.
Should you have questions on usage, please open an issue and ask – this helps to write useful documentation.
Feel free to contact on Slack in #haskell on GraphQL. You can obtain an invitation here.
