In a Rust project of mine, I have constructors that build convenient instances of some types.
Let's say I model a fridge with apples:
struct Apple {};
struct Fridge {
apples: Vec<&apples>,
fn ready_fridge() -> Fridge {
Fridge { /* with 2 apples */ }
}
}
I'd like the read_fridge()
constructor to prepare a fridge with two apples; how can I do that?
It's not directly possible, because the apples are allocated on the stack, so they can't be returned.
I tried with lazy_static
, however, it gets messy (and I couldn't make it work anyway).
Is there any way? Maybe, the design is wrong, instead?
