In OSS we _may_ look for a environment variable or fall back to the default value.

Constructors

Fields

runCheckFeatureFlag :: FeatureFlag -> IO Bool
Action that samples the value of a feature flag. Different products will want to do different things. For example, the Cloud product will want to use LaunchDarkly whereas the OSS and non-cloud EE products will want to sample environment variables.
listKnownFeatureFlags :: [(FeatureFlag, Text)]
A registry of flags that are known by the system. This is only used to inform of feature flag values via the 'v1alphaconfig' endpoint. Ideally, the console should have a dedicated endpoint to sample feature flags so we don't _have_ to centralise that knowledge here.
