Enum BuildError 

pub enum BuildError {
    FailedToCreateRuntime(String),
    FailedToCreateHTTPListener(String),
    FailedToSetGlobalRecorder(SetRecorderError<PrometheusRecorder>),
    InvalidAllowlistAddress(String),
    InvalidPushGatewayEndpoint(String),
    MissingExporterConfiguration,
    EmptyBucketsOrQuantiles,
    ZeroBucketDuration,
}

Errors that could occur while building or installing a Prometheus recorder/exporter.

Variants

FailedToCreateRuntime(String)

There was an issue when creating the necessary Tokio runtime to launch the exporter.

FailedToCreateHTTPListener(String)

There was an issue when creating the HTTP listener.

FailedToSetGlobalRecorder(SetRecorderError<PrometheusRecorder>)

Installing the recorder did not succeed.

InvalidAllowlistAddress(String)

The given address could not be parsed successfully as an IP address/subnet.

InvalidPushGatewayEndpoint(String)

The given push gateway endpoint is not a valid URI.

MissingExporterConfiguration

No exporter configuration was present.

This generally only occurs when HTTP listener support is disabled, but no push gateway configuration was give to the builder.

EmptyBucketsOrQuantiles

Bucket bounds or quantiles were empty.

ZeroBucketDuration

Bucket duration cannot be zero.

Trait Implementations

impl Debug for BuildError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for BuildError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for BuildError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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 #99301)

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

impl From<SetRecorderError<PrometheusRecorder>> for BuildError

fn from(source: SetRecorderError<PrometheusRecorder>) -> BuildError

Converts to this type from the input type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
