SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Rust developers often need an integrated mechanism to toggle features in production without redeploys, and this skill provides a cohesive PostHog-driven approach to flag evaluation in Rust apps.

Core Features & Use Cases

  • Boolean feature flags using is_feature_enabled to enable/disable code paths based on user or system context.
  • Multivariate feature flags with get_feature_flag to select among variants and tailor behavior.
  • Payload retrieval via get_feature_flag_payload to adapt UI or logic based on flag-provided data.
  • Fetch all flags with get_feature_flags to inspect all active flags for a user, analytics, and debugging.
  • Override evaluation with optional person, groups, or group properties to tailor flag decisions in server or backend code.

Quick Start

Install the PostHog Rust crate, initialize the client, and replace hardcoded branches with is_feature_enabled or get_feature_flag calls to drive conditional logic.

FAQPage Schema
How do I add PostHog feature flags to a Rust backend?

You can fetch all active feature flags for a user in Rust by calling the get_feature_flags function, which allows you to inspect active flags for analytics and debugging.

How do I retrieve multivariate feature flag variants in Rust?

To retrieve multivariate feature flag variants in Rust, use the get_feature_flag function to select among variants and tailor application behavior based on the returned flag value.

Can I use person and group properties to override feature flag evaluation in Rust?

Yes, you can override feature flag evaluation in Rust by providing optional person, groups, or group properties to tailor flag decisions in server or backend code.

How do I get feature flag payloads for Rust CLI tools?

You can get feature flag payloads for Rust CLI tools by using the get_feature_flag_payload function, which retrieves flag-provided data to adapt logic without needing redeploys.
