Struct RouteAllowList 

pub struct RouteAllowList { /* private fields */ }

Set of route templates that the metrics middleware is willing to emit as the route label value. Anything not in the set collapses to UNKNOWN_ROUTE.

Cloned into request extensions at server start so the http_metrics_middleware body does not need to capture the allow-list via a type-erased closure. The set is wrapped in Arc so the per-request clone is a single refcount bump.

Implementations

impl RouteAllowList

pub fn new_default() -> Self

pub fn from_static(routes: &'static [&'static str]) -> Self

Construct an allow-list from an explicit &'static str slice. Used by integration tests that want to assert on a non-default route set.

true if route is on the allow-list.
