Package registry provides a non-standalone implementation of
|
|
MeterProvider that adds uniqueness checking for instrument descriptors
|
|
on top of other MeterProvider it wraps.
|
|
|
|
This package is currently in a pre-GA phase. Backwards incompatible changes
|
|
may be introduced in subsequent minor version releases as we work to track the
|
|
evolving OpenTelemetry specification and user feedback.
