Struct FieldError 

pub struct FieldError {
    pub location: Vec<LocationItem>,
    pub code: Cow<'static, str>,
    pub message: String,
}

A single field-level validation failure.

Fields

location: Vec<LocationItem>

Path from the validated root to the failing value.

code: Cow<'static, str>

Stable machine-readable error code.

message: String

Human-readable explanation.

Implementations

impl FieldError

pub fn new( code: impl Into<Cow<'static, str>>, message: impl Into<String>, ) -> Self

Create a field error with an empty location path.

pub fn at(self, item: impl Into<LocationItem>) -> Self

Prepend a location segment so nested errors can bubble toward the root.

Trait Implementations

impl Clone for FieldError

fn clone(&self) -> FieldError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FieldError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for FieldError

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

Formats the value using the given formatter.

impl Eq for FieldError

impl Error for FieldError

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<FieldError> for ValidationError

fn from(error: FieldError) -> Self

Converts to this type from the input type.

impl PartialEq for FieldError

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for FieldError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
