This library provides a set of useful macros for creating [std collections], similar to the
default vec! macro
These macros enable list/map comprehension similar to what's present in python.
For example, the following python code
list = [x*x for x in range(0,10)]
dict = {x : x*x for x in range(0,10)}
is equivalent to the following rust code
let list = list![x*x; x in 0..10];
let dict = map!{x => x*x; x in 0..10};
With maps, you can also use identifiers as keys, which are then converted to &'static str keys.
map!{
field1: 0,
field2: 1
};
You can't repeat fields with this notation. The following will give a runtime error.
should_panic
map!{
field1: 0,
field1: 1
};
