Feature flags

Section titled “Feature flags”

Lychee supports several feature flags:

  • native-tls enables the platform-native TLS crate native-tls.
  • vendored-openssl compiles and statically links a copy of OpenSSL. See the corresponding feature of the openssl crate.
  • rustls-tls enables the alternative TLS crate rustls.
  • email-check enables checking email addresses using the check-if-email-exists crate. This feature requires the native-tls feature.
  • check_example_domains allows checking example domains such as example.com. This feature is useful for testing.

By default, native-tls and email-check are enabled.
