Cargo Features

[dependencies]
launchdarkly-server-sdk = { version = "2.1.0", default-features = false, features = ["rustls"] }
default = rustls

The rustls feature is set by default whenever launchdarkly-server-sdk is added without default-features = false somewhere in the dependency tree.

rustls default

Enables rustls of eventsource-client, http1 and http2 of hyper-rustls ^0.24.1

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.

hyper-rustls rustls

Enables hyper-rustls ^0.24.1
