graphql-schema-diff

]

该Crate实现了两个GraphQL模式的差异比较，返回一个变更列表。它为Grafbase的变更日志功能和操作检查提供支持。

示例

use graphql_schema_diff::{diff, Change, ChangeKind};

let source = r#"
  type Pizza {
    id: ID!
    name: String!
    toppings: [Topping!]!
  }

  enum Topping {
    OLIVES
    MUSHROOMS
    PINEAPPLE
  }
"#;

let target = r#"
  type Pizza {
    id: ID!
    name: PizzaName
    toppings: [Topping!]!
  }

  type PizzaName {
    english: String
    italian: String!
  }

  enum Topping {
    OLIVES
    MUSHROOMS
    POTATO
  }
"#;

let changes = diff(source, target).unwrap();

assert_eq!(changes,
   &[
        Change {
            path: String::from("Pizza.name"),
            kind: ChangeKind::ChangeFieldType
        },
        Change {
            path: String::from("PizzaName"),
            kind: ChangeKind::AddObjectType
        },
        Change {
            path: String::from("Topping.PINEAPPLE"),
            kind: ChangeKind::RemoveEnumValue
        },
        Change {
            path: String::from("Topping.POTATO"),
            kind: ChangeKind::AddEnumValue
        }
]);

Cargo特性

• serde: 为Change实现Serialize和Deserialize接口（默认：开启）。
