Struct ReplayGuard 

pub struct ReplayGuard { /* private fields */ }

Sliding-window replay guard for message deduplication.

Tracks seen message IDs within a configurable time window and rejects duplicates. Use with Envelope::open_with_replay_guard for transport-level replay protection.

Examples

use ma_core::ReplayGuard;

let mut guard = ReplayGuard::new(120); // 2-minute window
// or use the default (120 seconds):
let mut guard = ReplayGuard::default();
