Function analyze_feature_flags_with_session 

pub fn analyze_feature_flags_with_session(
    session: &AnalysisSession,
) -> EngineResult<FeatureFlagsAnalysis>

Run feature flag analysis with a reusable analysis session.

Errors

Returns crate::EngineError::cancelled when the session’s caller cancelled the run. The scan spends its time in the parse loop and in the dead-code correlation behind it, and both observe the token. A session without a cancellation token can never return this error.
