Visualize rust struct call graph within one crate

1

Hi there,

I have a project which is growing more and more. I realize that lots of structures are too much intertwined: struct A calls struct B which calls back struct A through struct C, and such things.

Is there a good tool to draw this callgraph in a nice way, so that it's easy recognizable where I should change these dependencies?

This is NOT about crate-dependencies, which are the only results that show up with a google search. But I'm interested to see the dependencies between the structs in the same crate.

Thanks for any hint,

Linus

There are a couple crates out there that seem to offer this service, although I have not personally tried them:

They are probably using a library like petgraph to construct the call graph from your code base.
