Struct ValidationErrors 

pub struct ValidationErrors<'a> { /* private fields */ }

An owned collection of validation errors that implements std::error::Error.

Obtain this by calling ErrorIterator::into_errors().

Implementations

impl<'a> ValidationErrors<'a>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn as_slice(&self) -> &[ValidationError<'a>]

Returns the errors as a slice.

pub fn iter(&self) -> Iter<'_, ValidationError<'a>>

pub fn iter_mut(&mut self) -> IterMut<'_, ValidationError<'a>>

Trait Implementations

impl Debug for ValidationErrors<'_>

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

Formats the value using the given formatter.

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<'a> IntoIterator for ValidationErrors<'a>

type Item = ValidationError<'a>
