Struct ParseMetricError 

pub struct ParseMetricError(/* private fields */);

Error returned by Metric::from_str when the input is not a recognised metric name.

Holds the offending input verbatim. This type deliberately stays out of message policy and only carries the rejected input, so the wrapper layer can format the user-facing message however it wants. A front end parsing a user’s metric selection wants crate::metric_catalog::resolve_selector instead, which takes the wider CLI vocabulary and whose error carries a did-you-mean hint.

Implementations

impl ParseMetricError

pub fn input(&self) -> &str

The rejected input that failed to parse as a Metric name.

Lets callers recover the offending string programmatically rather than scraping it out of the Display output.

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
