Enum prometheus_http_query::error::Error

#[non_exhaustive]
pub enum Error {
    Client(Error),
    ApiError(ApiError),
    EmptySeriesSelector,
    UrlParse(ParseError),
    ResponseParse(Error),
    MissingField(MissingFieldError),
}

A global error enum that encapsulates other more specific types of errors.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Client(Error)

Wraps errors from the underlying reqwest::Client that cannot be mapped to a more specific error type.

ApiError(ApiError)

Occurs when Prometheus responds with e.g. HTTP 4xx (e.g. due to a syntax error in a PromQL query).
Details on the error as reported by Prometheus are included in ApiError.

EmptySeriesSelector

UrlParse(ParseError)

ResponseParse(Error)

MissingField(MissingFieldError)

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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)

Provides type based access to context intended for error reports.
