* [Book](https://async-graphql.github.io/async-graphql/en/index.html)
* [中文文档](https://async-graphql.github.io/async-graphql/zh-CN/index.html)
* [Docs](https://docs.rs/async-graphql)
* [GitHub repository](https://github.com/async-graphql/async-graphql)
* [Cargo package](https://crates.io/crates/async-graphql)
* Minimum supported Rust version: 1.46 or later
## Safety
This crate uses `#![forbid(unsafe_code)]` to ensure everything is implemented in 100% Safe Rust.
## Features
* Fully supports async/await
* Type safety
* Rustfmt friendly (Procedural Macro)
* Custom scalars
* Minimal overhead
* Easy integration (actix_web, tide, warp, rocket ...)
* Upload files (Multipart request)
* Subscriptions (WebSocket transport)
* Custom extensions
* Apollo Tracing extension
* Limit query complexity/depth
* Error Extensions
* Apollo Federation
* Batch Queries
# Crate features
This crate offers the following features, all of which are activated by default:
- `apollo_tracing`: Enable the [Apollo tracing extension](extensions/struct.ApolloTracing.html).
- `log`: Enable the [logger extension](extensions/struct.Logger.html).
- `tracing`: Enable the [tracing extension](extensions/struct.Tracing.html).
- `multipart`: Support [sending files over HTTP multipart](http/fn.receive_body.html).
- `unblock`: Support [asynchronous reader for Upload](types/struct.Upload.html)
- `bson`: Integrate with the [`bson` crate](https://crates.io/crates/bson).
- `chrono`: Integrate with the [`chrono` crate](https://crates.io/crates/chrono).
- `chrono-tz`: Integrate with the [`chrono-tz` crate](https://crates.io/crates/chrono-tz).
- `url`: Integrate with the [`url` crate](https://crates.io/crates/url).
- `uuid`: Integrate with the [`uuid` crate](https://crates.io/crates/uuid).
## Examples
If you are just getting started, we recommend checking out our examples at: https://github.com/async-graphql/examples
To see how you would create a Relay-compliant server using async-graphql, warp, diesel & postgresql, you can also check out a real-world example at: https://github.com/phated/twentyfive-stars
## Benchmark
Ensure that there is no CPU-heavy process in background!
```shell script
cd benchmark
#measure all with system malloc
cargo bench
#measure only chat run
cargo bench -- "chat run"
#measure all with jemalloc
cargo bench --features jemalloc
#measure only simple run with jemalloc
cargo bench --features jemalloc -- "simple run"
```
Now HTML report is available at `benchmark/target/criterion/report`
