[boost] Is there a one-to-one map class in boost?

Hello,

Now I'm finding a one-to-one map class, say map1, that support the following syntax:

map1 m;

m.insert(std::make_pair(k1, v1));
...
key k;
value v;

v = m[k];
k = m[v];

I know a pair of std::map could provide such functionality. But I think a single obj, if that class
exists, would be more elegant.

Is there such a class in boost?

Thanks
Max
