Hello, I've been using PRBTest for a project where we need to do some gas calculations, but there are no methods to pause and resume gas metering, i.e. pauseGasMetering() and resumeGasMetering(), as in Vm from forge-std.

Thought I should let you know.

Thank you for taking the time to report this.

The problem is that I have to maintain a copy of the Vm interface, and I sometimes miss the latest updates in Forge Std. It looks like these gas metering cheats have been added in this PR.

I will add them shortly in PRBTest and ship a new version (v0.5.5) so you can start using them right away.

Related: I just made a proposal in the Forge Std repo to modularize the Vm interface to a dedicated repo:

foundry-rs/forge-std#353

Done in v0.5.5

@urataps - after upgrading, you should be able to use the pauseGasMetering and resumeGasMetering cheatcodes with PRBTest.
