acme-proxy-admin 0.6.1

//! `/ui/profiles/{name}/filter` — the policy behind one endpoint.
//!
//! Read-only, like its API twin and for the same two reasons: a policy is
//! configuration, so there is nothing here for a route to write, and
//! `filter explain` deliberately has no web surface at all. This file
//! therefore contributes nothing to
//! `tests/admin_pages.rs::mutating_page_endpoints()`. See
//! [`crate::webadmin::handlers::filter`] for both arguments in full, including
//! why this shows the *live* policy where the CLI rebuilds one.
