Cargo Features

[dependencies]
tracing-opentelemetry = { version = "0.28.0", default-features = false, features = ["metrics", "metrics_gauge_unstable", "tracing-log", "async-trait", "futures-util", "lazy_static", "thiserror"] }

default = metrics, tracing-log

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