Expand description
Creates a new HashSet
instance.
This macro can be used in two forms:
- Without arguments, it creates an empty
HashSet
. - With elements, it creates a
HashSet
and inserts the provided elements into it.
ยงExamples
Creating an empty HashSet
:
use std_macro_extensions::*;
let my_set: HashSet<i32> = hash_set!();
Creating a HashSet
with elements:
use std_macro_extensions::*;
let my_set = hash_set!(1, 2, 3);
