Struct LimitLoadBalancer 

pub struct LimitLoadBalancer<T>
where
    T: Send + Sync + Clone + 'static,
{ /* private fields */ }

A load balancer that limits the number of allocations per entry over a specified time interval.

This implementation supports both async and sync allocation.

Implementations

impl<T> LimitLoadBalancer<T>

where T: Send + Sync + Clone + 'static,

pub fn new(entries: Vec<(u64, T)>) -> Self

Create a new LimitLoadBalancer with the default interval of 1 second.

Arguments

• entries - A vector of tuples (max_count, value).

pub fn new_interval(entries: Vec<(u64, T)>, interval: Duration) -> Self

Create a new LimitLoadBalancer with a custom interval duration.

Arguments

• entries - A vector of tuples (max_count, value).
• interval - Duration after which allocation counts are reset.

pub async fn update<F, R, N>(&self, handle: F) -> Result<N>

where F: Fn(Arc<LimitLoadBalancerRef<T>>) -> R, R: Future<Output = Result<N>>,

Update the load balancer using an async callback.

pub async fn alloc_skip(&self, index: usize) -> (usize, T)

Asynchronously allocate an entry, skipping the specified index. Loops until a valid entry is found.

pub fn try_alloc_skip(&self, index: usize) -> Option<(usize, T)>

Try to allocate an entry without awaiting. Returns None immediately if no entry is available.
