Struct InvocationSlot 

pub struct InvocationSlot { /* private fields */ }

RAII guard around an active-invocation slot. Increments the per-function counter on creation; decrements when dropped. Used by invoke() so the slot is always released, even when the underlying executor panics.

Implementations

impl InvocationSlot

pub fn acquire(state: &LambdaState, function_name: &str) -> Arc<AtomicU32>

pub fn from_acquired(counter: Arc<AtomicU32>) -> Self

Construct from an already-incremented counter handle. The caller is responsible for ensuring the counter was bumped via acquire; the guard handles the decrement.

pub fn current(state: &LambdaState, function_name: &str) -> u32

Peek the current in-flight count for function_name without incrementing. Returns 0 when no entry exists.

Trait Implementations

impl Drop for InvocationSlot

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.
