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:

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

Thanks for any insights here!

From your description it sounds like you want OnceCell which is a relatively new feature; previously you'd use lazy_static

Yeah I tried out lazy_static, but the compiler was strongly urging me not to use it since it's being deprecated. Thanks, I didn't know about OneCell.
