Struct ValidationItem 

pub struct ValidationItem {
    pub field: String,
    pub message: String,
    pub code: Option<String>,
}

A single field-level validation error.

Used within the "errors" extension key to report multiple validation failures in a structured format suitable for frontend form binding.

Example

use rust_rfc7807::ValidationItem;

let item = ValidationItem::new("email", "must be a valid email address")
    .code("INVALID_EMAIL");

let json = serde_json::to_value(&item).unwrap();
assert_eq!(json["field"], "email");
assert_eq!(json["code"], "INVALID_EMAIL");

Fields

field: String

The field path that failed validation (e.g., "email" or "address.zip").

message: String

A human-readable description of the validation failure.

code: Option<String>

An optional machine-readable error code for this specific validation failure.

Implementations

impl ValidationItem

pub fn new(field: impl Into<String>, message: impl Into<String>) -> Self

Create a new validation item for the given field and message.

pub fn code(self, code: impl Into<String>) -> Self

Set an error code for this validation item.

Trait Implementations

impl Clone for ValidationItem

fn clone(&self) -> ValidationItem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationItem

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ValidationItem

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ValidationItem

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ValidationItem

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
