I just saw the developer preview for Rust and wanted to try it out.

I'm trying to find all calls tolen() on aStringobject.

pubfnname_length(name:String) ->usize{    name.len()}

I expected it to work like this but there is no method for accessing the type information.
I saw other languages having thisgetType() function. Is Rust different here?

import rustfromMethodCallExprcallwherecall.getIdentifier().toString()="len"andcall.getReceiver().getType().toString()="String"selectcall

From looking at the AST it seems I could get theTypeRepr from the function argument by tracing it back via dataflow analysis.
But I'm thinking there must be an easier way?
I'm new to codeql.
