Struct ValidationErrors 

pub struct ValidationErrors { /* private fields */ }

Available on crate feature core and non-WebAssembly only.

Aggregates validation errors by field name.

Collects per-field ValidationErrors and provides access to the accumulated errors for structured error responses.

Implementations

impl ValidationErrors

pub fn new() -> ValidationErrors

Available on crate feature validators only.

Create an empty error collection.

pub fn add( &mut self, field: impl Into<Cow<'static, str>>, error: ValidationError, )

Available on crate feature validators only.

Add a validation error for a specific field.

pub fn field_errors(&self) -> &BTreeMap<Cow<'static, str>, Vec<ValidationError>>

Available on crate feature validators only.

Get all field errors as a map.

pub fn is_empty(&self) -> bool

Available on crate feature validators only.

Returns true if no errors have been added.

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 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 From<ValidationErrors> for Error

fn from(err: ValidationErrors) -> Error

Converts to this type from the input type.

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.
