Describes an error encountered when validating an OptimizeToursRequest.

Fields

code: i32

A validation error is defined by the pair (code, display_name) which are always present.

Other fields (below) provide more context about the error.

MULTIPLE ERRORS: When there are multiple errors, the validation process tries to output several of them. Much like a compiler, this is an imperfect process. Some validation errors will be “fatal”, meaning that they stop the entire validation process. This is the case for display_name="UNSPECIFIED" errors, among others. Some may cause the validation process to skip other errors.

STABILITY: code and display_name should be very stable. But new codes and display names may appear over time, which may cause a given (invalid) request to yield a different (code, display_name) pair because the new error hid the old one (see “MULTIPLE ERRORS”).

display_name: String

The error display name.

fields: Vec<FieldReference>

An error context may involve 0, 1 (most of the time) or more fields. For example, referring to vehicle #4 and shipment #2’s first pickup can be done as follows:

fields { name: "vehicles" index: 4}
fields { name: "shipments" index: 2 sub_field {name: "pickups" index: 0} }

Note, however, that the cardinality of fields should not change for a given error code.

error_message: String

Human-readable string describing the error. There is a 1:1 mapping between code and error_message (when code != “UNSPECIFIED”).

STABILITY: Not stable: the error message associated to a given code may change (hopefully to clarify it) over time. Please rely on the display_name and code instead.

offending_values: String

May contain the value(s) of the field(s). This is not always available. You should absolutely not rely on it and use it only for manual model debugging.

Trait Implementations
