Struct ValidationErrors 

pub struct ValidationErrors {
    pub errors: Vec<ValidationError>,
    pub fields: BTreeMap<String, FieldErrors>,
}

Container for validation errors with nested structure support.

Example

use skp_validator_core::{ValidationErrors, ValidationError};

let mut errors = ValidationErrors::new();
errors.add_field_error("email", ValidationError::new("email", "email.invalid", "Invalid email"));
errors.add_field_error("name", ValidationError::new("name", "required", "Name is required"));

assert_eq!(errors.count(), 2);

Fields

errors: Vec<ValidationError>

Root-level errors (struct-wide validations)

fields: BTreeMap<String, FieldErrors>

Field-level errors

Implementations

impl ValidationErrors

pub fn new() -> ValidationErrors

Create an empty error container

pub fn from_error(error: ValidationError) -> ValidationErrors

Create from a single error

pub fn is_empty(&self) -> bool

Check if there are no errors

pub fn count(&self) -> usize

Count total errors recursively

pub fn add_root_error(&mut self, error: ValidationError)

Add a root-level error (not associated with a specific field)

pub fn add_field_error( &mut self, field: impl Into<String>, error: ValidationError, )

Add a field-level error

pub fn add_nested_errors( &mut self, field: impl Into<String>, errors: ValidationErrors, )

Add nested struct errors

pub fn add_list_errors( &mut self, field: impl Into<String>, errors: BTreeMap<usize, Box<ValidationErrors>>, )

Add list item errors

pub fn add_map_errors( &mut self, field: impl Into<String>, errors: BTreeMap<String, Box<ValidationErrors>>, )

Add map item errors

pub fn merge(&mut self, other: ValidationErrors)

Merge another ValidationErrors into this one

pub fn merge_result<T>( &mut self, result: Result<T, ValidationErrors>, ) -> Option<T>

Merge errors from a Result

pub fn to_flat_map(&self) -> BTreeMap<String, Vec<String>>

Convert to a flat map format: “path” -> [“error1”, “error2”]

Useful for simpler error handling or compatibility with other formats.

pub fn messages(&self) -> Vec<String>

Get all error messages as a flat list

pub fn field(&self, name: &str) -> Option<&FieldErrors>

Get errors for a specific field

pub fn has_field_error(&self, name: &str) -> bool

Check if a specific field has errors

pub fn field_count(&self) -> usize

Get the number of fields with errors

pub fn field_errors(&self) -> impl Iterator<Item = (&String, &FieldErrors)>

Iterate over field errors

pub fn to_json(&self) -> Value

Convert to JSON value (requires serde feature)

pub fn to_json_string(&self) -> String

Convert to JSON string (requires serde feature)

pub fn to_json_pretty(&self) -> String

Convert to pretty JSON string (requires serde feature)

Trait Implementations

impl Clone for ValidationErrors

fn clone(&self) -> ValidationErrors

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationErrors

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

Formats the value using the given formatter.

impl Default for ValidationErrors

fn default() -> ValidationErrors

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ValidationErrors

fn deserialize<__D>( __deserializer: __D, ) -> Result<ValidationErrors, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ValidationErrors

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

Formats the value using the given formatter.

impl Error for ValidationErrors

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 FromIterator<ValidationError> for ValidationErrors

fn from_iter<I>(iter: I) -> ValidationErrors

where I: IntoIterator<Item = ValidationError>,

Creates a value from an iterator.

impl Serialize for ValidationErrors

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
