Building an end-to-end solution as a package

In the previous section, we identified what we needed to do to build our catastrophe model package. We can achieve it with the following steps:

1. Build a footprint merging process.
2. Build a vulnerability and probability merging process.
3. Build a Python interface in Rust.
4. Build an interface in Python.
5. Build package installation instructions.

Before we build anything, we must define our dependencies in our Cargo.toml file with the following code:

[package]
name = "flitton_oasis_risk_modelling"
version = "0.1.0"
authors = ["Maxwell Flitton <[e-mail]>"]
edition = "2018"
[dependencies]
csv = "1.1"
serde = { version = "1", features = ["derive"] }
[lib]
name = "flitton_oasis_risk_modelling"
crate-type=["rlib", "cdylib"]
[dependencies.pyo3]
version = "0.13.2"
features = ["extension...
