Struct PoolOptions 

pub struct PoolOptions {
    pub isolate: IsolateConfig,
    pub desired_size: usize,
    pub max_size: usize,
    pub max_queue: Option<usize>,
    pub queue_mode: QueueMode,

}

Configuration for bundle pools.

Fields

isolate: IsolateConfig

Baseline isolate options (Pyodide version, warm snapshot hooks, etc.).

desired_size: usize

Preferred number of isolates to keep hot.

max_size: usize

Upper bound on isolates that may be spawned when demand spikes.

max_queue: Option<usize>

Optional maximum number of queued calls awaiting an idle isolate.

queue_mode: QueueMode

Behaviour when the queue is full (Block vs FailFast).

lifecycle_hooks: Option<LifecycleHooks>

Optional lifecycle callbacks invoked around isolate/call events.

memory_limit_kib: Option<u64>

RSS guard rail in KiB; isolates exceeding it are quarantined.

heap_limit_kib: Option<u64>

Pyodide heap guard rail in KiB; isolates exceeding it are quarantined.

telemetry_interval: Option<Duration>

Interval for the periodic telemetry reporter (set to None to disable).
