Implementations

impl ValidationError

pub const INTERNAL_CODE: &'static str = "__internal__"

Code used by ValidationError::internal.

pub fn new(code: &'static str) -> ValidationError

pub fn internal(error: impl Display) -> ValidationError

An error that is not the client’s fault (e.g. a database lookup inside a custom validator failed). The code is __internal__ and the message is error’s Display text.

web-core turns validation results containing such an error into a 500 (something_went_wrong!) instead of a 400 field-validation error.

use web_core_validator::ValidationError;

let err = ValidationError::internal("connection refused");
assert!(err.is_internal());
assert_eq!(err.message.as_deref(), Some("connection refused"));

pub fn is_internal(&self) -> bool

Whether this error was created with ValidationError::internal.

pub fn add_param<T: Serialize>(&mut self, name: Cow<'static, str>, val: &T)

pub fn with_message(self, message: Cow<'static, str>) -> ValidationError

Adds a custom message to a ValidationError that will be used when displaying the ValidationError, instead of an auto-generated description.

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ValidationError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

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 source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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<(&str, &str)> for ValidationError

fn from((code, message): (&str, &str)) -> Self

Converts to this type from the input type.

impl From<(&str, Vec<Option<&str>>)> for ValidationError

fn from(value: (&str, Vec<Option<&str>>)) -> Self

Converts to this type from the input type.

impl PartialEq for ValidationError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for ValidationError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
