graphql-tools (Rust)

Documentation | Crate | GitHub

The graphql_tools crate implements tooling around GraphQL for Rust libraries. Most of the tools are based on traits and structs implemented in graphql_parser crate.

The goal of this library is to create a common layer of tools that has similar/improved APIs to graphql-js reference implementation and graphql-tools from the JS/TS ecosystem.

Getting Started

Add graphql-tools as a dependency of your project by adding the following to your Cargo.toml file:

[dependencies]
graphql-tools = "..."

Or, if you are using cargo-edit:

cargo add graphql-tools

By default, this crate is using the graphql-parser library for parsing. If you wish to use an alternative implementation such as graphql-hive/graphql-parser-hive-fork, use the following features setup:

[dependencies]
graphql-tools = { version = "...", features = "graphql_parser_fork", default-features = false }

Validation Rules

This comparison is based on graphql-js reference implementation.
