The initial release of metriki instrumentation for r2d2.

This module provides metrics support for r2d2 and diesel database connection pool. It monitors performance and usage of your database connections. The release has metrics for:

• Histogram to record connection borrow time
• Meter to measure connection borrow rate, aka database qps
• Histogram to record connection usage time, aka the time to execute your db query
• Meter to measure connection borrow failure rate

These metrics are useful for tracking performance of database-driven applications, together with APIs-level metrics.

For more information, check docs.rs.

Initial release of the metriki-tracing module.

This module acts as a subscriber layer of trace. It helps collect spans and events with metriki meter and timer. So you can use tracing API for metriki functionality together with metriki reporters and exporters.

See example and docs for its usage.
