Trait Implementations

impl Default for FeatureManager

fn default() -> Self

Creates a new FeatureManager with safe, batteries-included defaults:

1. MemoryFeatureDriver (programmatic/testing overrides)

3. TomlFeatureDriver (local TOML file configuration via Rullst.toml)
4. DbFeatureDriver when the orm feature is enabled (database-backed flags, requires an initialized database pool)
