Description
I am currently trying to port https://github.com/nrc/callgraph.rs/ to the current nightly and updated it for the changes on rustc_private and rustc_save_analysis. The goal is to parse the saved analysis to extract a call graph.
The saved anaysis seems to work, function calls are detected correctly. However, my code does not work on method calls (like Foo::m1() or foo.m2(), because neither SaveContext::get_expr_data nor SaveContext::get_path_data returns some data on the nodes when iterating the AST and requesting analysis data.
What is the correct way of getting analysis data for method calls ? Did I miss something on the analysis ?
The code is here https://github.com/chifflier/callgraph.rs (the visitor code is here: https://github.com/chifflier/callgraph.rs/blob/master/src/visitor.rs) and I am testing using cargo run examples/methods.rs
