Required Methods§
Sourcefn enabled<'life0, 'life1, 'async_trait>(
&'life0 self,
flag: &'life1 str,
) -> Pin<Box<dyn Future<Output = Option<bool>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
fn enabled<'life0, 'life1, 'async_trait>(
&'life0 self,
flag: &'life1 str,
) -> Pin<Box<dyn Future<Output = Option<bool>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
Check if a feature flag is enabled.

Retrieve the variation name assigned to a specific target identifier.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
