Defined in:
lib/feature_hub/sdk/local_yaml_store.rb,
sig/feature_hub/featurehub.rbs

Overview

Reads feature flags from a local YAML file and loads them into a FeatureHubRepository, allowing the SDK to operate without a FeatureHub Edge server. Implements RawUpdateFeatureListener but silently ignores all incoming update callbacks — the file is the single source of truth and is read exactly once at initialization.

Expected YAML format (same as LocalYamlValueInterceptor):

flagValues:
MY_FLAG: true
MY_STRING: "hello"
MY_NUMBER: 42
