Overview

Package ast provides an AST of a GraphQL query or schema.

This package's API is UNSTABLE. New members may be added at any time, or renamed/moved.

Design notes: this package should consist of simple structs, and perhaps some marshaling code. No business logic, should just be storage of a parsed document
