    ($duration:expr, || $expr:expr) => { ... };
}

Available on crate feature std only.

Throttles the execution of an expression to run at most once per specified duration.

Uses static variables with lazy initialization to track the last execution time. Thread-safe via atomic operations.

Examples

use std::time::Duration;
use reth_tracing::throttle;

// Log at most once per second.
throttle!(Duration::from_secs(1), || {
    tracing::info!("This message is throttled");
});
