Struct metrics_util::debugging::DebuggingRecorder

source ·
pub struct DebuggingRecorder { /* private fields */ }
Available on crate feature debugging only.
Expand description

A simplistic recorder that can be installed and used for debugging or testing.

Callers can easily take snapshots of the metrics at any given time and get access to the raw values.
