'Small map' optimization: store up to a small number of key-value pairs on the stack.

Provides '1:1' API compatibility with std::collections::HashMap.

Example

use compact_map::CompactMap;

fn main() {
    let mut map = CompactMap::default(); // default capacity is 16
    // or you can specify the capacity
    // let mut map: CompactMap<&str, i32, 32> = CompactMap::default();

    map.insert("a", 1);
    map.insert("b", 2);
}
