Struct PvaStateConfig 

pub struct PvaStateConfig {
    pub max_channels: usize,
    pub channel_ttl: Duration,
    pub max_operations: usize,
    pub max_update_rate: usize,
    pub max_memory_bytes: usize,
    pub max_search_cache_entries: usize,
}

Configuration for the PVA state tracker

Fields

max_channels: usize

Maximum number of channels to track (default: 40000)

channel_ttl: Duration

Time-to-live for channel entries (default: 5 minutes)

max_operations: usize

Maximum number of operations to track per connection

max_update_rate: usize

Maximum update timestamps kept per connection for rate calculation (default: 10000)

max_memory_bytes: usize

Ceiling on tracked state in bytes, as reported by PvaStateTracker::memory_estimate.

When the estimate exceeds this, cleanup_expired sheds state in priority order – debug affordances first, decoded introspection last – so that a long-running passive observer accumulates coverage without growing without bound. 0 disables the ceiling.

max_search_cache_entries: usize

Hard cap on SEARCH name-cache entries, enforced independently of the memory ceiling so the caches cannot dominate a small budget.

Implementations

impl PvaStateConfig

pub fn new(max_channels: usize, ttl_secs: u64) -> Self

pub fn with_max_update_rate(self, max_update_rate: usize) -> Self

pub fn with_max_memory_bytes(self, max_memory_bytes: usize) -> Self

Set the memory ceiling. 0 disables shedding entirely.

pub fn with_max_operations(self, max_operations: usize) -> Self

Set the per-connection operation cap.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PvaStateConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PvaStateConfig

fn default() -> Self

Returns the “default value” for a type.
