Implementations

impl FormFieldValidationError

pub fn invalid_value<T: Into<String>>(value: T) -> Self

Creates a new FormFieldValidationError for an invalid value of a field.

pub fn maximum_length_exceeded(max_length: u32) -> Self

Creates a new FormFieldValidationError for a field value that is too long.

pub const fn from_string(message: String) -> Self

Creates a new FormFieldValidationError from a String.

pub const fn from_static(message: &'static str) -> Self

Creates a new FormFieldValidationError from a static string.

Trait Implementations

impl Debug for FormFieldValidationError

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

Formats the value using the given formatter.

impl Display for FormFieldValidationError

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

Formats the value using the given formatter.

impl Error for FormFieldValidationError

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 PartialEq for FormFieldValidationError

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