Struct MemoryFeatureDriver 

#[non_exhaustive]
pub struct MemoryFeatureDriver { /* private fields */ }

Memory-backed feature flag driver. Perfect for programmatic overrides and tests.

Implementations

impl MemoryFeatureDriver

pub fn new() -> Self

Creates a new MemoryFeatureDriver.

pub fn override_enabled(&self, flag: &str, enabled: bool)

Explicitly override a flag state.

pub fn override_rollout(&self, flag: &str, percentage: u32)

Explicitly override a percentage rollout rule (e.g. 30%).

pub fn override_variants(&self, flag: &str, variants: Vec<(String, u32)>)

Explicitly override an A/B split configuration (e.g. [(“a”, 50), (“b”, 50)]).

Trait Implementations

impl Default for MemoryFeatureDriver
