Overview

Package featureflags provides typed feature flags backed by environment variables. Each flag is read from an environment variable named CACHEW_FF_<NAME> (uppercased) and JSON-decoded into the flag's type. If the variable is unset, the flag returns its default value. Supported types are int and bool.
