Cargo Features

[dependencies]
pingora-core = { version = "0.1.1", default-features = false, features = ["openssl", "boringssl", "patched_http1"] }
default = openssl

The openssl feature is set by default whenever pingora-core is added without default-features = false somewhere in the dependency tree.

openssl default = pingora-openssl
boringssl = pingora-boringssl
patched_http1

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.

pingora-openssl openssl
pingora-boringssl boringssl?
