I'm not familiar with this format. Do you have any examples of storing hashmap data in env var values like this in the wild? If possible I'd like to align...

What is like to avoid is inventing a new syntax for env variables Can you link me to some example of those tools?

I'm wondering if it might be more useful to assume less about the structure of values and just treat structured data as `serde::Serialize` types. Env vars place a design constraint...

> export TEST_KEY="value" and export TEST_KEY2="value2" [Prefixed](https://lessis.me/envy/envy/fn.prefixed.html) var names are supported but carry a different but common convention. They namespace vars targeting an application

Hi @ExpHP. I'm a little confused by your example and what you mean by "compose". Your example with `Chemical` seems correct. You're derive a way to deserialize a chemical struct...

Oh that's interesting. This crate relies heavily on serde and I'm not sure that serde provides that hook but I can do some investigation.

Hi @Boscop thanks for reaching out. Very interesting usecase. Envy leverages a type called [IntoDersializer](https://docs.serde.rs/serde/de/trait.IntoDeserializer.html) to deserialize spefic types. Without looking closely I would have believe types that derive deserialize...
