Struct metrics_prometheus::metric::Fallible

pub struct Fallible<M>(pub Arc<Result<Arc<Metric<M>>>>);

Fallible Metric stored in metrics::Registry.

We’re obligated to store Fallible metrics inside metrics::Registry, because panicking earlier, rather than inside directly called metrics::Recorder methods, will poison locks the metrics::Registry is built upon on.

Tuple Fields

0: Arc<Result<Arc<Metric<M>>>>

Implementations

impl<M> Fallible<M>

pub fn as_ref(&self) -> Result<&Arc<Metric<M>>, &Error>

Mimics Result::as_ref() method for this Fallible.

Errors
