pub struct Service { /* private fields */ }

Implementations

impl Service

pub fn counter<L: Clone + Debug + EncodeLabelSet + Eq + Hash + Send + Sync + 'static>( self, name: impl AsRef<str>, description: impl AsRef<str>, ) -> Self

pub fn gauge<L: Clone + Debug + EncodeLabelSet + Eq + Hash + Send + Sync + 'static>( self, name: impl AsRef<str>, description: impl AsRef<str>, ) -> Self

pub fn histogram<L: Clone + Debug + EncodeLabelSet + Eq + Hash + Send + Sync + 'static>( self, name: impl AsRef<str>, description: impl AsRef<str>, buckets: &[f64], ) -> Self

pub fn run<CFG>(self, svc: impl FnOnce(CFG) + Clone + UnwindSafe) -> !

where CFG: ServiceConfig + Clone + Debug + Sync + Send + UnwindSafe,

Run the service under suitable supervision.

The name given influences the names of metrics and the environment variables that will be examined to determine the service configuration, while the svc function is what you provide as the entrypoint to the service to be run. If that function exits (which it shouldn’t), or panics (which it definitely shouldn’t, but might), it will be restarted.

Panics

As this function doesn’t normally exit, it will panic if any fatal error occurs, such as if the logger cannot be started, or if the service configuration cannot be correctly extracted from the environment.
