Feature flags of opentelemetry

Cargo Features

[dependencies]
opentelemetry_sdk = { version = "0.27.0", default-features = false, features = ["trace", "jaeger_remote_sampler", "logs", "spec_unstable_logs_enabled", "metrics", "rt-tokio", "rt-tokio-current-thread", "rt-async-std", "experimental_metrics_periodic_reader_no_runtime", "spec_unstable_metrics_views", "testing", "internal-logs"] }

default = internal-logs, logs, metrics, trace

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

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.
