Struct ValidationError

pub struct ValidationError<'a> {
    pub instance: Cow<'a, Value>,
    pub kind: ValidationErrorKind,
    pub instance_path: Location,
    pub schema_path: Location,
}

An error that can occur during validation.

Fields

instance: Cow<'a, Value>

Value of the property that failed validation.

kind: ValidationErrorKind

Type of validation error.

instance_path: Location

Path to the value that failed validation.

schema_path: Location

Path to the JSON Schema keyword that failed validation.

Implementations

impl<'a> ValidationError<'a>

Shortcuts for creation of specific error kinds.

pub fn masked<'b>(&'b self) -> MaskedValidationError<'a, 'b, 'static>

Returns a wrapper that masks instance values in error messages. Uses “value” as a default placeholder.

pub fn masked_with<'b, 'c>( &'b self, placeholder: impl Into<Cow<'c, str>>, ) -> MaskedValidationError<'a, 'b, 'c>

Returns a wrapper that masks instance values in error messages with a custom placeholder.

pub fn to_owned(self) -> ValidationError<'static>

Converts the ValidationError into an owned version with 'static lifetime.

pub fn custom( location: Location, instance_path: Location, instance: &'a Value, message: impl Into<String>, ) -> ValidationError<'a>

Create a new custom validation error.

Trait Implementations

impl<'a> Debug for ValidationError<'a>

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

Formats the value using the given formatter.

impl Display for ValidationError<'_>

Textual representation of various validation errors.

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<Error> for ValidationError<'_>

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for ValidationError<'_>

fn from(err: FromUtf8Error) -> Self

Converts to this type from the input type.

impl From<ValidationError<'_>> for ErrorDescription

fn from(e: ValidationError<'_>) -> Self

Converts to this type from the input type.
