Struct ValidationErrors 

pub struct ValidationErrors { /* private fields */ }

Collection of validation errors (guaranteed non-empty when constructed).

This type is only constructed when validation fails, so it always contains at least one error. Use ValidationErrorCollector during validation, then convert to this type only when errors are present.

The is_empty method is intentionally omitted because this type is guaranteed to be non-empty by construction.

Implementations

impl ValidationErrors

pub fn from_vec(errors: Vec<ValidationError>) -> Self

Creates a new ValidationErrors from a non-empty vector.

Panics

Panics if the vector is empty. Use try_from_vec for a fallible version.

pub fn try_from_vec(errors: Vec<ValidationError>) -> Option<Self>

Creates a new ValidationErrors from a vector, returning None if empty.

pub fn len(&self) -> usize

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

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

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 From<ValidationErrors> for OperationError

fn from(source: ValidationErrors) -> Self

Converts to this type from the input type.

impl<'a> IntoIterator for &'a ValidationErrors

type Item = &'a ValidationError

The type of the elements being iterated over.

type IntoIter = Box<dyn Iterator<Item = &'a ValidationError> + 'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for ValidationErrors

type Item = ValidationError

The type of the elements being iterated over.

type IntoIter = IntoIter<ValidationError>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
