Enum Validated

pub enum Validated<E> {
    Error(E),
    ValidationError(Box<ValidationError>),
}

A wrapper for error types of functions that can return validation errors.

Variants

Error(E)

A non-validation error occurred.

ValidationError(Box<ValidationError>)

A validation error occurred.

Implementations

impl<E> Validated<E>

pub fn map<F>(self, f: impl FnOnce(E) -> F) -> Validated<F>

Maps the inner Error value using the provided function, or does nothing if the value is ValidationError.

pub fn unwrap(self) -> E

Returns the inner Error value, or panics if it contains ValidationError.

Trait Implementations

impl<E: Clone> Clone for Validated<E>

fn clone(&self) -> Validated<E>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E> Debug for Validated<E>

where E: Display,

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

Formats the value using the given formatter.

impl<E> Display for Validated<E>

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

Formats the value using the given formatter.

impl<E> Error for Validated<E>

where E: Error + 'static,

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.
