# decorator
A project showcasing the example from the [Emulating callable objects](https://pyo3.rs/latest/class/call.html) chapter of the guide.
## Building and Testing
To build this package, first install `maturin`:
```shell
pip install maturin
```
To build and test use `maturin develop`:
```shell
pip install -r requirements-dev.txt
maturin develop
pytest
```
Alternatively, install nox and run the tests inside an isolated environment:
```shell
nox
```
## Copying this example
Use [`cargo-generate`](https://crates.io/crates/cargo-generate):
```bash
$ cargo install cargo-generate
$ cargo generate --git https://github.com/PyO3/pyo3 examples/decorator
```
(`cargo generate` will take a little while to clone the PyO3 repo first; be patient when waiting for the command to run.)
