Struct form_validation::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)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<Key> From<ValidationError<Key>> for ValidationErrors<Key> where
    Key: Clone + PartialEq, 

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

Performs the conversion.

impl<Key> PartialEq<ValidationErrors<Key>> for ValidationErrors<Key> where
    Key: PartialEq, 

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
