Struct OccupancyGuard 

pub struct OccupancyGuard<'a> { /* private fields */ }

RAII guard returned by RunAccountant::before_task_dispatch.

Holds an optional drop callback so host accountants can track in-flight concurrency or release per-dispatch leases when a step finishes or is cancelled (including when a for_each branch is dropped on fail-fast).

Implementations

impl<'a> OccupancyGuard<'a>

pub const fn noop() -> Self

A guard that does nothing when dropped.

pub fn new(on_drop: impl FnOnce() + Send + 'a) -> Self

A guard that runs on_drop once when dropped.

Trait Implementations

impl Debug for OccupancyGuard<'_>

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

Formats the value using the given formatter.

impl Default for OccupancyGuard<'_>

fn default() -> Self

Returns the “default value” for a type.

impl Drop for OccupancyGuard<'_>

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.
