Function metrics::set_recorder
source · pub fn set_recorder(
recorder: &'static dyn Recorder
) -> Result<(), SetRecorderError>
Expand description
Sets the global recorder to a &'static Recorder
.
This function may only be called once in the lifetime of a program. Any metrics recorded
before the call to set_recorder
occurs will be completely ignored.
This function does not typically need to be called manually. Metrics implementations should provide an initialization method that installs the recorder internally.
Errors
An error is returned if a recorder has already been set.
