## 📦 Getting Started
Add to your Cargo.toml as a dependency as follows:
```toml
[dependencies]
apdu = "0.3"
```

## 🛠 Longer payloads support
This library supports longer payloads of APDU commands and responses.
If you want to use these, turn `longer_payloads` feature on:

```toml
apdu-core = { version = "0.3", features = ["longer_payloads"] }
```

## 🛠 no_std support
apdu-core crate does support no_std environments (but it requires `alloc` yet).
If you are using this crate in no_std, turn `std` feature off by disabling default features:

```toml
[dependencies]
apdu-core = { version = "0.3", default-features = false }
```
