feature-targeting | Feature targeting system for K8s/Istio | Access Management library

feature-targeting is a Rust library typically used in Security, Access Management applications. feature-targeting has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Feature targeting is an evolution (or clarification) of the capability commonly referred to as feature toggles. The term "feature toggle" is a little misleading. Partly in mentioning "features", leading to an assumption that this capability is only useful for customer facing product changes, but mostly due to the assumption that features can be on or off for everyone and there is nothing in between. The key to feature targeting is allowing a feature (any behaviour of the system which is either new or different from what the majority of users see) to be enabled for a single user or any subset of users, selected according to set criteria, or randomly (but in a "sticky" fashion). This capability can then be used in place of a number of other commonly used risk-reducing strategies for testing, deployment and release of software, e.g. ephemeral and long-term environments, blue-green and canary deployments, etc. The goal of feature targeting is to fully separate deployments from releases and reduce complexity of IT infrastructure and automation, which is in place solely to make sure customers don't see behaviours which are not ready for the public and to reduce risk of issues caused by deployment.
