Struct PoolConfig 

pub struct PoolConfig {
    pub max_instances: usize,
    pub warm_count: usize,
}

Per-pool configuration.

Fields

max_instances: usize

Maximum concurrent live instances.

Bounds the wasmtime memory footprint. Default 4 matches the Capability::ConcurrentInstances default in the proposal. Acts as a concurrency semaphore: at most this many instances may be in flight at once.

warm_count: usize

Retained for API compatibility; no longer pre-warms anything.

Instances are now built fresh per InstancePool::acquire (so a reused store can’t leak guest state across calls), so there is no warm pool to populate. The field stays so existing PoolConfig { max_instances, warm_count } construction sites keep compiling and downstream config surfaces keep their shape.
