Cargo Features

[dependencies]
twistrs = { version = "0.6.3", default-features = false, features = ["smtp_lookup", "geoip_lookup", "whois_lookup"] }

default = smtp_lookup

The smtp_lookup feature is set by default whenever twistrs is added without default-features = false somewhere in the dependency tree.

smtp_lookup default = async-smtp

geoip_lookup = maxminddb

whois_lookup = whois-rust

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.
