Struct DispatchGuard 

pub struct DispatchGuard { /* private fields */ }

Removes a key from a shared DashMap<String, String> when dropped.

Create this guard (step 2) only after the key has already been inserted into the map (step 1) and before calling tokio::spawn (step 3). Moving the guard into the spawned async block ensures the key is removed regardless of whether the block completes normally or unwinds via a panic.

Implementations

impl DispatchGuard

pub fn new(map: Arc<DashMap<String, String>>, key: String) -> Self

Creates a guard that will remove key from map on drop.

The caller must have already inserted key into map.

Trait Implementations

impl Drop for DispatchGuard

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.
