Update 07-repeated-field.rs

env is mandatory field

[dtolnay]

I think the code is correct as written.

@dtolnay I got error in 07 testcase because env is None. Anything I missed?

If the user calls env n times, they need to get a vector of n environment variables. So for example they can call 2 times to get 2 elements in the vector (this is tested by assert_eq!(command.args, vec!["build", "--release"])). Or they call 0 times to get 0 elements in the vector.

thanks, I see your explanation
I interpret mandatory field is that user at least call 1 time, because env is not a Option field, so we should report error if no env is set by user
