Struct FieldViolation

pub struct FieldViolation {
    pub field: String,
    pub description: String,
    pub reason: String,
    pub localized_message: Option<LocalizedMessage>,
}

A message type used to describe a single bad request field.

Fields

field: String

A path that leads to a field in the request body. The value will be a sequence of dot-separated identifiers that identify a protocol buffer field.

Consider the following:

 message CreateContactRequest {
   message EmailAddress {
     enum Type {
       TYPE_UNSPECIFIED = 0;
       HOME = 1;
       WORK = 2;
     }

     optional string email = 1;
     repeated EmailType type = 2;
   }

   string full_name = 1;
   repeated EmailAddress email_addresses = 2;
 }

In this example, in proto field could take one of the following values:

• full_name for a violation in the full_name value
• email_addresses\[1\].email for a violation in the email field of the first email_addresses message
• email_addresses\[3\].type\[2\] for a violation in the second type value in the third email_addresses message.

In JSON, the same values are represented as:

• fullName for a violation in the fullName value
• emailAddresses\[1\].email for a violation in the email field of the first emailAddresses message
• emailAddresses\[3\].type\[2\] for a violation in the second type value in the third emailAddresses message.

description: String

A description of why the request element is bad.

reason: String

The reason of the field-level error. This is a constant value that identifies the proximate cause of the field-level error. It should uniquely identify the type of the FieldViolation within the scope of the google.rpc.ErrorInfo.domain. This should be at most 63 characters and match a regular expression of [A-Z][A-Z0-9_]+\[A-Z0-9\], which represents UPPER_SNAKE_CASE.

localized_message: Option<LocalizedMessage>

Provides a localized error message for field-level errors that is safe to return to the API consumer.

Trait Implementations

impl Clone for FieldViolation

fn clone(&self) -> FieldViolation

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FieldViolation

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for FieldViolation

fn default() -> FieldViolation

Returns the “default value” for a type.

impl Message for FieldViolation

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for FieldViolation

fn eq(&self, other: &FieldViolation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
