Enum PrometheusError 

pub enum PrometheusError {
    Conflict {
        name: String,
        source: Error,
    },
    InvalidCollector {
        name: String,
        source: Error,
    },
}

Construction failures of a PrometheusObserver.

Variants

Conflict

A collector with this name is already registered: by another observer (clone that observer instead of constructing a second one), by someone else, or with another schema. Use a unique prefix or another registry. The collectors registered before the collision were unregistered again; their names stay bound to the DialCache schema in that registry.

Fields

name: String

The fully qualified collector name that collided.

source: Error

The registry’s rejection.

InvalidCollector

The prometheus crate rejected a collector definition, which only a prefix that is not a valid metric name fragment can cause.

Fields

name: String

The fully qualified collector name that was rejected.

source: Error

The crate’s rejection.

Trait Implementations

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
