## `resumeGasMetering`

### Signature

```solidity
function resumeGasMetering() external;
```

### Description

Resumes gas metering (i.e., `gasleft()` will decrease as operations are executed). Gas usage will resume at the same amount at which it was paused.

### Examples

```solidity [test/ResumeGasMetering.t.sol]
function testResumeGasMetering() public {
    uint256 gasBefore = gasleft();
    
    vm.pauseGasMetering();
    // This section doesn't consume gas
    expensiveSetup();
    vm.resumeGasMetering();
    
    // Gas metering resumes here
    myContract.doSomething();
    
    uint256 gasUsed = gasBefore - gasleft();
    // gasUsed only reflects doSomething(), not expensiveSetup()
}
```
