Functions

func ReuseMetricWithMetadatasProto added in v0.15.0 

func ReuseMetricWithMetadatasProto(pb *metricpb.MetricWithMetadatas)

ReuseMetricWithMetadatasProto allows for zero-alloc reuse of *metricpb.MetricWithMetadatas by deep resetting the internal slices and when using gogoprotobuf's unmarshal function will reuse the slices and byte buffers already allocated on the message itself.

It is required to use nullable: false annotations so that it does not use pointer types for slices on the message to achieve zero alloc resets.

The methods resets the metric with metadatas proto, and in particular message fields that are slices because the `Unmarshal` generated from gogoprotobuf simply append a new entry at the end of the slice, and as such, the fields with slice types need to be reset to be zero-length. NB: reset only needs to be done to the top-level slice fields as the individual items in the slice are created afresh during unmarshaling.
