Struct PendingFlowsConfig 

pub struct PendingFlowsConfig {
    pub max_pending_flows: usize,
    pub max_entries_per_template: usize,
    pub max_entry_size_bytes: usize,
    pub ttl: Option<Duration>,
}

Configuration for pending flow caching.

When enabled, flows that arrive before their template are cached. When the template later arrives, cached flows are automatically re-parsed and included in the output.

Disabled by default; enable via the builder pattern.

Fields

max_pending_flows: usize

Maximum number of template IDs to track in the LRU pending cache.

max_entries_per_template: usize

Maximum number of pending flow entries per template ID. Prevents unbounded memory growth from a flood of data for a single unknown template.

max_entry_size_bytes: usize

Maximum size in bytes of a single pending flow entry’s raw data. Entries exceeding this limit are dropped to prevent memory exhaustion from oversized flowset bodies. Default: 65535 (u16::MAX).

ttl: Option<Duration>

TTL for pending flows. None means pending flows never expire (only evicted by LRU or per-template cap).
