Rust SDK for Fuel. It can be used for a variety of things, including but not limited to:

- Compiling, deploying, and testing [Sway](https://github.com/FuelLabs/sway) contracts;
- Launching a local Fuel network;
- Crafting and signing transactions with hand-crafted scripts or contract calls;
- Generating type-safe Rust bindings of contract methods;
- And more, `fuels-rs` is still in active development.

## FAQ

### What dependencies do I need?

- [The latest `stable` Rust toolchain](https://docs.fuel.network/guides/installation/#installing-rust);
- [`forc` and `fuel-core` binaries](https://docs.fuel.network/guides/installation/#installing-the-fuel-toolchain-using-fuelup).

### How can I run the SDK tests?

First, build the test projects using `forc`:

```shell
forc build --release --path e2e
```

Then you can run the SDK tests with:

```shell
cargo test
```

You can also run specific tests. The following example will run all integration tests in `types.rs` whose names contain `in_vector` and show their outputs:

```shell
cargo test --test types in_vector -- --show-output
```

### How to run WASM tests?

You need to have wasm32 as a target, if you don't already:

```shell
 rustup target add wasm32-unknown-unknown
```

You also need `wasm-pack`, if you don't already:

```shell
cargo install wasm-pack
```

Navigate to `packages/wasm-tests` and run `wasm-pack test`.

### What to do if my tests are failing on `master`

Before doing anything else, try all these commands:

```shell
cargo clean
rm Cargo.lock
forc build --release --path e2e
cargo test
```

### Why is the prefix `fuels` and not `fuel`?

In order to make the SDK for Fuel feel familiar with those coming from the [ethers.js](https://github.com/ethers-io/ethers.js) ecosystem, this project opted for an `s` at the end. The `fuels-*` family of SDKs is inspired by The Ethers Project.

### How can I run the docs locally?

Install `mdbook` by running:

```shell
cargo install mdbook
```

Next, navigate to the `docs` folder and run the command below to start a local server and open a new tab in your browser.

```shell
mdbook serve --open
```
