Native tracers support

[ValentinAndreevich]

Component

Anvil

Describe the feature you would like

debug_traceCall is useful for getting an execution trace of eth_call, expecially when it comes to tx simulation. That will be very nice if you are able to add callTracer support as a tracing option.

+1, callTracer support would be nice

this is being worked on separately on https://github.com/paradigmxyz/reth where these are already implemented, there will soon be some consolidation efforts to reduce duplicate code.

If someone wants to add this functionality via copy-paste to anvil until this is done, I'm happy to give pointers.

One more requirement, I got the trace like this:

{
    "depth": 1,
    "gas": 29978936,
    "gasCost": 3,
    "op": "PUSH1",
    "pc": 0,
    "stack": []
},

however, when I use debug_traceTransaction, I got

{
    "depth": 0,
    "error": "",
    "gas": 39469,
    "gasCost": 3,
    "memory": [],
    "op": "PUSH1",
    "pc": 0,
    "stack": [],
    "storage": {}
},

can we add storage and memory part?

could you give me some pointers?

what do you mean pointers, the storage and memory like

{
    "depth": 0,
    "error": "",
    "gas": 39469,
    "gasCost": 3,
    "memory": [],
    "op": "PUSH1",
    "pc": 0,
    "stack": [],
    "storage": {}
},

pointers meaning instructions/help on how to implement this into anvil

I do not dive deep into how we implement this. But I think you could refer to how debug_traceTransaction does. It won't be hard.
