Struct RateTracker 

pub struct RateTracker { /* private fields */ }

Thread-safe in-memory rate tracker.

Tracks action timestamps per agent DID using sliding windows. Not persistent — resets on process restart (by design; DATs are short-lived and rate limits are best-effort).

Implementations

impl RateTracker

pub fn new() -> Self

Create a new rate tracker with standard 1-hour and 24-hour windows.

pub fn record_action(&self, agent_did: &str)

Record an action for the given agent.

pub fn get_counts(&self, agent_did: &str) -> (u64, u64, u64)

Get current rate counts for an agent: (hourly, daily, concurrent).

pub fn acquire_concurrent(&self, agent_did: &str)

Increment the concurrent operation count for an agent.

pub fn release_concurrent(&self, agent_did: &str)

Decrement the concurrent operation count for an agent.
