Enum glean::ErrorType

source ·
#[repr(C)]
pub enum ErrorType { InvalidValue = 0, InvalidLabel = 1, InvalidState = 2, InvalidOverflow = 3, }
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.

Variants§

§

InvalidValue = 0

For when the value to be recorded does not match the metric-specific restrictions

§

InvalidLabel = 1

For when the label of a labeled metric does not match the restrictions

§

InvalidState = 2

For when the metric caught an invalid state while recording

§

InvalidOverflow = 3

For when the value to be recorded overflows the metric-specific upper range
