Gurkle

GraphQL client for Rust, with typed requests and responses, and subscriptions!

Features

• Precise types for query variables and responses.
• Supports GraphQL fragments, objects, unions, inputs, enums, custom scalars and input objects.
• Subscriptions support.
• Copies documentation from the GraphQL schema to the generated Rust code.
• Arbitrary derives on the generated responses.
• Arbitrary custom scalars.
• Supports multiple operations per query document.
• Supports setting GraphQL fields as deprecated and having the Rust compiler check their use.

Usage

• Install the CLI tool (cargo install gurkle-cli)
• Run gurkle generate --schema-path <your schema> path/to/operations/*.graphql
• This will generate a generated.rs in your current directory.
• include!("./generated.rs") into the .rs file of your choice
  • You may need to import types used by the custom scalars into this file, or use type definitions.

Custom scalars

The generated code will reference the scalar types as defined in the server schema. This means you have to provide matching rust types in the scope of the struct under derive. It can be as simple as declarations like type Email = String;. This gives you complete freedom on how to treat custom scalars, as long as they can be deserialized.

Deprecations

The generated code has support for @deprecated field annotations.

Documentation for the generated modules

You can use cargo doc --document-private-items to generate rustdoc documentation on the generated code.
