Rust

My program is small enough that in TS/JS I'd normally just store the data in some global variable to be access from whatever elsewhere in the app. But with Rust from what I can tell this doesn't seem to be a common practice. How should i handle this?

More specifically, I need to:

1. program start, fetch data from my db (DONE)
2. store this data somehow somewhere
3. access said data (for read only in this use case)

Thanks for any insights here!
