TimingMiddleware

Struct TimingMiddleware 

Source
pub struct TimingMiddleware { /* private fields */ }
Expand description

Middleware that measures query execution time.

This is a lightweight middleware that only adds timing information to the response. For more comprehensive metrics, use MetricsMiddleware.

Implementations§
