Struct ManagerBuilder 

pub struct ManagerBuilder<C, const N: usize> { /* private fields */ }

Builder for Manager.

Required

• weight_limit — maximum total weight before eviction
• eviction_cb — callback invoked for each evicted (key, weight) pair
• shutdown — watch receiver that signals actors to stop

Example

let manager = Manager::<32>::builder(limit, eviction_cb, shutdown_rx, runtime_handle)
    .capacity(10_000)
    .build();

Implementations

impl<C, const N: usize> ManagerBuilder<C, N>

where C: AsyncEvictionCallback<CacheEntryKey>,

pub fn capacity(self, capacity: usize) -> Self

Set the estimated per-shard capacity for preallocation.

pub fn len_watermark(self, watermark: usize) -> Self

Set an optional item-count watermark.

pub fn num_eviction_workers(self, n: usize) -> Self

Set the number of concurrent eviction worker tasks. Defaults to N (one per shard).

pub fn build(self) -> Manager<N>

Build the Manager, spawning shard actors and eviction workers.

Must be called within a tokio runtime context.
