Struct UnknownSelectorError 

pub struct UnknownSelectorError { /* private fields */ }

Error returned by resolve_selector for a name that is no metric selector.

Carries the rejected input and the did-you-mean candidates, drawn from selector_names. Display renders unknown metric: <input>[; did you mean …]; known metrics: <names>, the message the Python bindings raise; its exact wording is not SemVer-protected. A front end that wants its own wording composes it from input, suggestions and selector_names.

Implementations

impl UnknownSelectorError

pub fn input(&self) -> &str

The rejected input, verbatim.

pub fn suggestions(&self) -> &[&'static str]

The selector_names closest to the input, best first; empty when nothing is close. At most three, all tied on closeness.

impl Error for UnknownSelectorError

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
