-> PyOxidizer <-
================

Packaging and distributing python applications.

---

-> Use cases <-
================

- deploying single binary for python projects
- packaging python project with dependencies
- at the same time use rust integration stuff

---

-> Installation <-
==================

- python - `pip install pyoxidizer`
- rust - `cargo install pyoxidizer`
- package manager

---

-> First impression <-
======================

- Confusing usage and docs
- Two entrypoints? `init-config-file` vs `init-rust-project`?

---

-> Entrypoints <-
=================

- `init-config-file`
  - creates blank project with a config file 
  - defaults to python interpreter
- `init-rust-project`
  - it is really a rust project
  - ... invoking the python interpreter
  - Why? ¯\\_(ツ)_/¯
- compared to the others this is harder to setup but more features around
  python rust integration

-> Side tips <-
===============

When experimenting with pyoxidizer, you may want to use sccache to
improve the build time it you run it quite often.

How slow? ~40s -> ~30s (incremental)
Just set `RUSTC_WRAPPER=sccache`.

---

-> Conclusion <-
================

- not easy to use although there are documentation (even hello world)
