Is there already something that prints the callgraphs in something graphviz could consume?
I don't think callgraphs are sth we have code to emit. Would be a nice feature of rustdoc though
do we have ast-view though?
I think an ast-view should be a stable tool built on top of
syn, not some compiler-magic
call graphs require more info, but it should be fairly simple to write a custom driver that dumps a .dot file for every function in a crate
Yes, I wouldn't want to duplicate effort and I hoped something would be available since everybody likes pretty graphs :)
