Struct ValidationErrors 

pub struct ValidationErrors {
    pub fields: HashMap<String, Vec<RuleError>>,
}

Collection of validation errors for multiple fields.

Fields

fields: HashMap<String, Vec<RuleError>>

Map of field name to list of errors for that field

Implementations

impl ValidationErrors

pub fn new() -> Self

Create an empty validation errors collection.

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

Add an error for a field.

pub fn add_all(&mut self, field: impl Into<String>, errors: Vec<RuleError>)

Add multiple errors for a field.

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

Merge another ValidationErrors into this one.

pub fn is_empty(&self) -> bool

Check if there are any errors.

pub fn len(&self) -> usize

Get the total number of errors.

pub fn get(&self, field: &str) -> Option<&Vec<RuleError>>

Get errors for a specific field.

pub fn into_result(self) -> Result<(), Self>

Convert to Result - Ok if no errors, Err otherwise.

pub fn field_names(&self) -> Vec<&str>

Get all field names with errors.

pub fn to_api_error(&self) -> ApiValidationError

Convert to the standard RustAPI error format.

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

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<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ValidationErrors

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

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 Serialize for ValidationErrors

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
