Struct ValidationErrors

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

A collection of ValidationErrors as a result of validating the fields of a form.

Fields

errors: Vec<ValidationError<Key>>

Implementations

impl<Key> ValidationErrors<Key>

where Key: PartialEq + Clone,

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

Create a new ValidationErrors.

pub fn get(&self, key: &Key) -> Option<ValidationErrors<Key>>

Get errors associated with the specified field key, or None if there are no errors for that field.

pub fn is_empty(&self) -> bool

Returns true if there are no errors in this collection.

pub fn extend(&mut self, errors: ValidationErrors<Key>)

Extend this collection of errors with the contents of another collection.

pub fn len(&self) -> usize

The number of errors in this collection.

Trait Implementations

impl<Key: Clone> Clone for ValidationErrors<Key>

fn clone(&self) -> ValidationErrors<Key>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Key: Debug> Debug for ValidationErrors<Key>

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

Formats the value using the given formatter.

impl<Key> Default for ValidationErrors<Key>

fn default() -> Self

Returns the “default value” for a type.

impl<Key> Display for ValidationErrors<Key>

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

Formats the value using the given formatter.

impl<Key> Error for ValidationErrors<Key>

where Key: Debug,

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<Key> From<ValidationError<Key>> for ValidationErrors<Key>

where Key: Clone + PartialEq,

fn from(err: ValidationError<Key>) -> Self

Converts to this type from the input type.

impl<Key> PartialEq for ValidationErrors<Key>

where Key: PartialEq,

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