provides common macros like hash_map!
Rust crate providing some common macros.
Currently following macros are exported:
hash_map!
hash_set!
b_tree_map!
b_tree_set!
const_expr_count!
use std::collections::HashMap;
use common_macros::hash_map;
fn main() {
let map_a = hash_map! {
"foo" => vec![0,1,2],
"bar" => vec![3,4,5]
};
// expands to roughly
let map_b = {
let mut map = HashMap::with_capacity(2);
map.insert("foo", vec![0,1,2]);
map.insert("bar", vec![3,4,5]);
map
};
assert_eq!(map_a, map_b);
}
