ancestors_at_offset

Returns ancestors of the node at the offset, sorted by length. This should do the right thing at an edge, e.g. when searching for expressions at { $0foo } we will get the name reference instead of the whole block, which we would get if we just did find_token_at_offset(...). flat_map(|t| t.parent().ancestors()).

find_node_at_offset

Finds a node of specific Ast type at offset. Note that this is slightly imprecise: if the cursor is strictly between two nodes of the desired type, as in
