Struct ConnectionCounter 

pub struct ConnectionCounter { /* private fields */ }

Connection counter for tracking active connections.

This is designed to be wrapped in Arc and shared across async tasks. Use try_acquire_arc to get a guard that can be moved into spawned tasks.

impl ConnectionCounter

pub fn new(max: usize) -> Self

Create a new connection counter.

pub fn try_acquire_arc(self: &Arc<Self>) -> Option<ConnectionGuard>

Try to acquire a connection slot (for use when counter is in Arc).

pub fn current(&self) -> usize

pub fn max(&self) -> usize
