Struct Registry 

pub struct Registry { /* private fields */ }

Wraps prometheus::Registry with an embedded Filter so that register_*_with_registry! macros can decide at construction time whether a metric should be active.

Implementations

impl Registry

pub fn new() -> Self

Creates a registry whose filter is read from METRICS_FILTER env var.

pub fn new_custom( prefix: Option<String>, labels: Option<HashMap<String, String>>, ) -> Result<Self>

Creates a custom-prefixed registry whose filter is read from the METRICS_FILTER env var.

pub fn with_filter(filter_str: &str) -> Self

Creates a registry using the supplied filter string.

pub fn is_enabled(&self, name: &str, module: &str) -> bool

Used by wrapper macros to decide whether to register a metric.

pub fn inner(&self) -> &Registry

Returns the underlying prometheus::Registry for use inside wrapper macros.

pub fn register(&self, c: Box<dyn Collector>) -> Result<()>

pub fn unregister(&self, c: Box<dyn Collector>) -> Result<()>

pub fn gather(&self) -> Vec<MetricFamily>
