Module metrics 

Structs

AgentDDSketch

DDSketch implementation based on the Datadog Agent.

BinMap

A split representation of sketch bins.

Config

Controller

Controller allows capturing metric snapshots.

MetricLabel

A label name that should be preserved on metric keys when present as a tracing-span field.

Enums

Error

Statics

LABELS

Snapshot of every registered MetricLabel, built on first access. inventory populates all submissions before main, so the snapshot is guaranteed to capture every entry — the hot path is then a single set lookup against this static.

Functions

init_global

Initialize the default metrics sub-system

init_test

Initialize the thread-local metrics sub-system. This function will loop until a recorder is actually set.
