pub struct ValidationErrors { /* private fields */ }

Collection of 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 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 errors(&self) -> &[ValidationError]

Get all errors

pub fn result(self) -> Result<(), Self>

Convert to Result, returning Err(self) when errors are present.

Errors

Returns Err(ValidationErrors) if any validation errors were added.

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 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 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.
