Struct ValidationErrors

pub struct ValidationErrors {
    pub errors: HashMap<String, Vec<ValidationError>>,
}

Collection of validation errors, typically one per field

Fields

errors: HashMap<String, Vec<ValidationError>>

Map of field names to their validation errors

Implementations

impl ValidationErrors

pub fn new() -> Self

Create a new empty validation errors collection

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

Add a single validation error

pub fn add_errors( &mut self, field: impl Into<String>, errors: Vec<ValidationError>, )

Add multiple validation errors for a field

pub fn add_error( &mut self, field: impl Into<String>, message: impl Into<String>, )

Add a simple validation error with field and message

pub fn is_empty(&self) -> bool

Check if there are any validation errors

pub fn len(&self) -> usize

Get the number of fields with errors

pub fn total_errors(&self) -> usize

Get total number of validation errors across all fields

pub fn get_field_errors(&self, field: &str) -> Option<&Vec<ValidationError>>

Get errors for a specific field

pub fn has_field_errors(&self, field: &str) -> bool

Check if a specific field has errors

pub fn merge(&mut self, other: ValidationErrors)

Merge another ValidationErrors into this one

pub fn from_error(error: ValidationError) -> Self

Create ValidationErrors from a single error

pub fn to_json(&self) -> Value

Convert to a JSON-serializable format for API responses

Trait Implementations

impl Clone for ValidationErrors

fn clone(&self) -> ValidationErrors

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationErrors

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

Formats the value using the given formatter.

impl Default for ValidationErrors

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ValidationErrors

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ValidationErrors

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

Formats the value using the given formatter.

impl Error for ValidationErrors

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 From<ValidationError> for ValidationErrors

fn from(error: ValidationError) -> Self

Converts to this type from the input type.

impl Serialize for ValidationErrors

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
