Assignment

To create or change a local variable, it is sufficient to use this construct:

#![allow(unused)]
fn main() {
Assign::local(&lv2_var!(n), expr)
}

It is possible to manipulate the global context using this variant:

#![allow(unused)]
fn main() {
Assign::global(&lv2_var!(n), expr)
}

There is even a way of setting the values on lists and dictionaries. Under the hood, Set is actually expecting a Ref as the target location - which is retrieved by Access - and overwrites the value inside. This is compatible with the way dictionaries and lists are internally constructed.

#![allow(unused)]
fn main() {
Assign::local(&lv2_var!(point), lv2_dict!());
Assign::set(&lv2_access!(point, x), x_coord);
Assign::set(&lv2_access!(point, y), y_coord);
}
