Function rsconf::enable_cfg

pub fn enable_cfg(name: &str)

Enables conditional compilation of code behind #[cfg(name)] or with if cfg!(name) (without quotes around name).

See set_cfg_value() to set a (name, value) tuple to enable conditional compilation of the form #[cfg(name = "value")] for cases where name is not a boolean cfg but rather takes any of several discrete values.

Note the different from #[cfg(feature = "name")]! The configuration is invisible to end users of your code (i.e. name does not appear anywhere in Cargo.toml) and does not participate in dependency resolution.
