Struct FieldErrors 

pub struct FieldErrors<K = String> { /* private fields */ }

A refused submission.

Resource::validate_record keys it by the record form’s field enum (FieldErrors<UserFormField>), so an error always names a field the form renders; one on an embedded value renders under its first control. The panel keys every error by the form key it renders under (FieldErrors, keyed by String), and Source::form reads them back when a schema renders.

Implementations

impl<K> FieldErrors<K>

pub fn new() -> Self

No errors.

pub fn add(&mut self, key: impl Into<K>, message: impl Into<String>)

Refuse key with message.

pub fn push(&mut self, error: FieldError<K>)

Refuse error’s key with error.

pub fn is_empty(&self) -> bool

Whether nothing was refused.

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

Every error, in the order it was added.

pub fn extend(&mut self, other: Self)

Append other’s errors after these.

impl FieldErrors

pub fn contains_key(&self, key: &str) -> bool

Whether any error renders under key.

pub fn first(&self, key: &str) -> Option<&FieldError>

The error key renders: the first one added.

Trait Implementations

impl<K: Debug> Debug for FieldErrors<K>

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

Formats the value using the given formatter.

impl<K> Default for FieldErrors<K>

fn default() -> Self

Returns the “default value” for a type.

impl<K> IntoIterator for FieldErrors<K>

type Item = FieldError<K>

The type of the elements being iterated over.

type IntoIter = IntoIter<FieldError<K>>

Which kind of iterator are we turning this into?
