Struct metrics_util::layers::RouterBuilder

pub struct RouterBuilder { /* private fields */ }

Routes metrics to specific target recorders.

Routes are defined as a prefix to check against the metric name, and a mask for the metric type. For example, a route with the pattern of “foo” would match “foo”, “or “foo.submetric”, but not “something.foo”. Likewise, a metric mask of “all” would apply this route to counters, gauges, and histograms, while any specific mask would only apply to the given metric kind.

A default route (recorder) is always present and used in the case that no specific route exists.

Implementations

impl RouterBuilder

pub fn from_recorder<R>(recorder: R) -> Self

where R: Recorder + 'static,

Creates a RouterBuilder from a Recorder.

The given recorder is used as the default route when no other specific route exists.

pub fn add_route<P, R>( &mut self, mask: MetricKindMask, pattern: P, recorder: R ) -> &mut RouterBuilder

where P: AsRef<str>, R: Recorder + 'static,

Adds a route.

mask defines which metric kinds will match the given route, and pattern is a prefix string used to match against metric names.

If a matching route already exists, it will be overwritten.

pub fn build(self) -> Router

Builds the configured Router.
