Record Class MetricId

java.lang.Object
java.lang.Record
cloud.opencode.base.observability.metric.MetricId
Record Components:
name - the metric name, must not be null or blank | 指标名称，不能为 null 或空白
tags - the immutable sorted list of tags | 不可变的排序标签列表
public record MetricId(String name, List<Tag> tags) extends Record
MetricId - Unique identifier for a metric, composed of name and tags MetricId - 指标的唯一标识符，由名称和标签组成

Tags are defensively copied and sorted by key for consistent equality semantics. Two MetricIds with the same name and same tags (regardless of original order) are equal.

标签进行防御性拷贝并按键排序，以确保一致的相等性语义。 具有相同名称和相同标签（无论原始顺序）的两个 MetricId 相等。
