:mrdocs:

Return a `balm::MetricId` object for the metric identified by the specified `category` and `name`. If no corresponding metric has already been registered, register a new metric and return a `balm::MetricId` object identifying that newly‐registered metric. The behavior is undefined unless `category` and `name` are null‐terminated. Note that this operation is guaranteed to return a valid `balm::MetricId` object.
