Cargo Features

[dependencies]
emit_otlp = { version = "0.11.0-alpha.21", default-features = false, features = ["gzip", "tls"] }
default = gzip, tls

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

gzip default = flate2
tls default = rustls-native-certs, tokio-rustls

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.
