Graphql解析器

此库包含GraphQL查询语言的完整解析器和格式化器，以及AST类型。

文档 | GitHub | Crate

当前此库支持完整的GraphQL语法，以及以下扩展

1. 订阅
2. 块（三引号字符串）
3. 模式定义语言/IDL（仍在RFC中）

示例：解析和格式化查询

use gurkle_parser::query::{parse_query, ParseError};

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

示例：解析和格式化模式

use gurkle_parser::schema::{parse_schema, ParseError};

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

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

type Query {
  users: [User!]!
}

\"\"\"
  Example user object

  This is just a demo comment.
\"\"\"
type User {
  name: String!
}
");
