Struct TestChangeGuard 

pub struct TestChangeGuard { /* private fields */ }

RAII guard for test changes that auto-reverts on drop.

This ensures that test changes are always cleaned up, even if the test panics or returns early.

Example

use std::path::Path;
use rch_common::test_change::{TestCodeChange, TestChangeGuard};

fn run_test() -> anyhow::Result<()> {
    let change = TestCodeChange::for_main_rs(Path::new("/my/project"))?;
    let guard = TestChangeGuard::new(change)?;
     
    // Do compilation and testing here...
    // File will be automatically reverted when guard goes out of scope
     
    Ok(())
}

Implementations

impl TestChangeGuard

pub fn new(change: TestCodeChange) -> Result<Self>

Create a new guard and apply the test change.

The change is applied immediately upon creation.

pub fn change_id(&self) -> &str

Get the change ID for this test modification.

pub fn file_path(&self) -> &Path

Get the path to the modified file.

pub fn verify_in_binary(&self, binary_path: &Path) -> Result<bool>

Check if the compiled binary contains the test marker.

pub fn revert(self) -> Result<()>

Manually revert the change without dropping the guard.

After calling this, the guard will not revert again on drop.

Trait Implementations

impl Drop for TestChangeGuard

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
