Bmesh Uv issues

Hi guys, i’ve another problem with bmesh:

now with the new structure, uv data are no more “set” in this way:

but are noe in this way:[0].data[i].uv

but with this i’ve only a list of vertices that it don’t correspond to the real vertices(i think) and it don’t have any face association.

so this is is the problem… i need a way to have a face(polygon) mapped on it’s relative vertices, a thing like this

vertex 0 = 0,0
vertex 1 = 0,1
vertex 2 = 1,1

face 0 = 0 1 2

there is a way? cause i’ve made an export script, but naturally it don’t work on bmesh…
