Struct ValidationErrors 

pub struct ValidationErrors { /* private fields */ }

A collection of validation errors.

Implementations

impl ValidationErrors

pub fn new() -> Self

Create an empty collection.

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

Add a validation error.

pub fn is_empty(&self) -> bool

Check if there are any errors.

pub fn len(&self) -> usize

Get the number of errors.

pub fn iter(&self) -> impl Iterator<Item = &ValidationError>

Get an iterator over the errors.

pub fn into_inner(self) -> Vec<ValidationError>

Convert into a vector of errors.

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

Merge another collection of errors into this one.

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() -> ValidationErrors

Returns the “default value” for a type.

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 From<Vec<ValidationError>> for ValidationErrors

fn from(errors: Vec<ValidationError>) -> Self

Converts to this type from the input type.

impl PartialEq for ValidationErrors

fn eq(&self, other: &ValidationErrors) -> 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.
