//! Graphql Parser
//! ==============
//!
//! This library contains full parser and formatter of the graphql
//! query language as well as AST types.
//!
//! [Docs](https://docs.rs/graphql-parser/) |
//! [Github](https://github.com/tailhook/graphql-parser/) |
//! [Crate](https://crates.io/crates/graphql-parser)
//!
//! Current this library supports full graphql syntax, and the following
//! extensions:
//!
//! 1. Subscriptions
//! 2. Block (triple quoted) strings
//!
//!
//! Example: Parse and Format Query
//! -------------------------------
//!
//! ```rust
//! # extern crate failure;
//! # extern crate graphql_parser;
//! use graphql_parser::parse_query;
//!
//! # fn parse() -> Result<(), failure::Error> {
//! let ast = parse_query("query MyQuery { field1, field2 }")?;
//! // Format canonical representation
//! assert_eq!(format!("{}", ast), "\
//! query MyQuery {
//!   field1
//!   field2
//! }
//! ");
//! # Ok(())
//! # }
//! # fn main() {
//! #    parse().unwrap()
//! # }
//! ```
//!
