Crate fast_telemetry_export 

Export adapters for fast-telemetry metrics.

This crate provides the I/O layer for getting fast-telemetry metrics out of your process: DogStatsD over UDP, OTLP over HTTP/protobuf, ClickHouse native TCP, span export, and stale-series sweeping.

Exporters are generic — they accept closures for metric serialization so they work with any metrics struct, not just a specific AllMetrics type.

Configuration highlights

• OTLP metrics and span exporters support custom service.name, instrumentation scope names, additional resource attributes, per-request headers, and request timeouts.
• OTLP exporters gzip-compress larger protobuf payloads automatically and use exponential backoff after transport failures.
• The span exporter also exposes max_batch_size to bound work per cycle.
• The stale-series sweeper expects the caller to invoke fast_telemetry::advance_cycle() once per sweep and then call each dynamic metric’s evict_stale(...) method.

Features

• dogstatsd (default) — DogStatsD UDP exporter
• otlp (default) — OTLP HTTP/protobuf metrics and span exporters
• clickhouse — ClickHouse native-protocol metrics exporter, including first-party rows and OTel-standard table support (via klickhouse)
