pub struct ValidationError { /* private fields */ }

Returned when one or more validation rules are violated.

Implementations

impl ValidationError

pub fn new(violations: Vec<Violation>) -> Self

Create a validation error from a list of violations.

pub fn single(violation: Violation) -> Self

Create a validation error containing a single violation.

pub fn violations(&self) -> &[Violation]

Returns all violations as a shared slice.

pub fn into_violations(self) -> Vec<Violation>

Consume and return the underlying violations vector.

pub fn is_empty(&self) -> bool

Returns true when there are no violations.

pub fn len(&self) -> usize

Returns the number of violations.

pub fn to_proto(&self) -> Violations

Convert to the wire-compatible buf.validate.Violations message.

Trait Implementations

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

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 From<ValidationError> for Error

fn from(source: ValidationError) -> Self

Converts to this type from the input type.
