pub enum ErrorType {
InvalidValue,
InvalidLabel,
InvalidState,
InvalidOverflow,
}
Expand description
The possible error types for metric recording.
Note: the cases in this enum must be kept in sync with the ones
in the platform-specific code (e.g. ErrorType.kt
) and with the
metrics in the registry files.
For when the value to be recorded does not match the metric-specific restrictions
For when the label of a labeled metric does not match the restrictions
For when the metric caught an invalid state while recording
For when the value to be recorded overflows the metric-specific upper range
The error type’s metric id
Return an iterator over all possible error types.
let errors = ErrorType::iter();
let all_errors = errors.collect::<Vec<_>>();

sufficient, and should not be overridden without very good reason.
