Graphql Parser

This library contains full parser and formatter of the graphql query language as well as AST types.

Example: Parse and Format Query

use graphql_tools::parser::query::{parse_query, ParseError};

let ast = parse_query::<&str>("query MyQuery { field1, field2 }")?;
// Format canonical representation
assert_eq!(format!("{}", ast), "\
query MyQuery {
  field1
  field2
}
");

Example: Parse and Format Schema

use graphql_tools::parser::schema::{parse_schema, ParseError};

let ast = parse_schema::<String>(r#"
    schema {
        query: Query
    }
    type Query {
        users: [User!]!,
    }
    """
       Example user object

       This is just a demo comment.
    """
    type User {
        name: String!,
    }
"#)?.to_owned();
// Format canonical representation
assert_eq!(format!("{}", ast), "\
schema {
  query: Query
}

type Query {
  users: [User!]!
}

\"\"\"
  Example user object

  This is just a demo comment.
