impl OperationGuard<'_>

pub(crate) fn finish<T, E>(self, result: &Result<T, E>)

Records success or failure and completes the operation.

Trait Implementations

impl Drop for OperationGuard<'_>

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.
