Struct ValidationError 

pub struct ValidationError {
    pub fields: Vec<FieldError>,
    pub message: String,
}

Validation error containing all field errors.

This type serializes to the standard RustAPI error format:

{
  "error": {
    "type": "validation_error",
    "message": "Validation failed",
    "fields": [...]
  }
}

Fields

fields: Vec<FieldError>

Collection of field-level validation errors

message: String

Custom error message (default: “Validation failed”)

Implementations

impl ValidationError

pub fn new(fields: Vec<FieldError>) -> Self

Create a new validation error with field errors.

pub fn with_message(fields: Vec<FieldError>, message: impl Into<String>) -> Self

Create a validation error with a custom message.

pub fn field( field: impl Into<String>, code: impl Into<String>, message: impl Into<String>, ) -> Self

Create a validation error for a single field.

pub fn is_empty(&self) -> bool

Check if there are any validation errors.

pub fn len(&self) -> usize

Get the number of field errors.

pub fn add(&mut self, error: FieldError)

Add a field error.

pub fn localize<T: Translator>(&self, translator: &T) -> Self

Localize validation errors using a translator.

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> ValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ValidationError

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl Serialize for ValidationError

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
