Dear Rust developers,
I have just started using rust so this is obviously a stupid question but I was
wondering why .iter() is needed when looping over the elements of an array? In
the following example:
let a = [1i, 2i, 3i];
for e in a.iter() {
println!("{}", e);
}
why can’t one simply write:
let a = [1i, 2i, 3i];
for e in a {
println!("{}", e);
}
and have the compiler figure out that ‘a’ has ‘.iter()’ and use it? The form
without .iter() just feels more natural to me in this case.
Please feel free to tell me to RTFM or ask this question elsewhere.
Regards,
Pim
