maplit 0.1.6

Macros for container literals with specific type.

#[macro_use] extern crate maplit;

# fn main() {
let map = hashmap!{
    "a" => 1,
    "b" => 2,
};
# }

The maplit crate uses => syntax for the mapping macros. It is not possible to use : as separator due to syntactic restrictions in regular macro_rules! macros.

Note that rust macros are flexible in which brackets you use for the invocation. You can use them as hashmap!{} or hashmap![] or hashmap!(). This crate suggests {} as the convention for the map & set macros, it matches their Debug output.

Generic container macros already exist elsewhere, so those are not provided here at the moment.
