serialize = serde, serde_json

add ons

default = http-proto, internal-logs, logs, metrics, reqwest-blocking-client, trace

These default features are set whenever opentelemetry-otlp is added without default-features = false somewhere in the dependency tree.

grpc-tonic experimental-grpc-retry? = http, prost, tokio, tonic, tonic-types

grpc using tonic

Enables gen-tonic of opentelemetry-proto

Affects opentelemetry-otlp::TonicExporterBuilderSet, opentelemetry-otlp::tonic_types, retry_classification::grpc, retry_classification::grpc.classify_tonic_status, opentelemetry-otlp::retry_classification, opentelemetry-otlp::retry…

gzip-tonic

Enables gzip of tonic

zstd-tonic

Enables zstd of tonic

experimental-grpc-retry = grpc-tonic

grpc with retry support

Enables experimental_async_runtime and rt-tokio of opentelemetry_sdk

Affects tonic::WithTonicConfig.with_retry_policy, retry::retry_with_backoff…

gzip-http = flate2

http compression

zstd-http = zstd

tls = tls-ring

Deprecated: use tls-ring or tls-aws-lc or tls-provider-agnostic

Affects tonic::WithTonicConfig.with_tls_config, opentelemetry-otlp::tonic_types.transport…

tls-ring tls?

Enables tls-ring of tonic

Affects tonic::WithTonicConfig.with_tls_config, opentelemetry-otlp::tonic_types.transport…

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
