Module features 

Feature flag evaluation.

Provides FeatureContext and FeatureChecker for evaluating feature flags stored in the options system.

Structs

FeatureChecker

FeatureContext

Application context passed to feature flag evaluation.

Enums

FeatureError

A handle for checking feature flags within a specific namespace. Why a feature could not be evaluated. Distinct from crate::OptionsError: an unset feature is not an error here (see FeatureChecker::try_has), and a value that fails to parse as a Feature is.

Functions

features

Get a feature checker handle for a namespace.
