Struct DepthLock 

pub struct DepthLock { /* private fields */ }

Depth lock holds a reference on the depth gauge. The drop ensures impl that the reference is decremented even if there is a panic unwind.

Implementations

impl DepthLock

pub fn obtain( depth_gauge: Arc<Mutex<DepthGauge>>, ) -> Result<DepthLock, StatusCode>

The depth lock tests if the depth can increment and then obtains a lock on it. The lock will decrement the depth when it drops to ensure proper behaviour during unwinding.

Trait Implementations

impl Debug for DepthLock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for DepthLock

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.
