Struct ValidationErrors

pub struct ValidationErrors(/* private fields */);

Implementations

impl ValidationErrors

pub fn new() -> ValidationErrors

pub fn has_error( result: &Result<(), ValidationErrors>, field: &'static str, ) -> bool

Returns a boolean indicating whether a validation result includes validation errors for a given field. May be used as a condition for performing nested struct validations on a field in the absence of field-level validation errors.

pub fn merge( parent: Result<(), ValidationErrors>, field: &'static str, child: Result<(), ValidationErrors>, ) -> Result<(), ValidationErrors>

Returns the combined outcome of a struct’s validation result along with the nested validation result for one of its fields.

pub fn merge_all( parent: Result<(), ValidationErrors>, field: &'static str, children: Vec<Result<(), ValidationErrors>>, ) -> Result<(), ValidationErrors>

Returns the combined outcome of a struct’s validation result along with the nested validation result for one of its fields where that field is a vector of validating structs.

pub fn errors(&self) -> &HashMap<&'static str, ValidationErrorsKind>

Returns a map of field-level validation errors found for the struct that was validated and any of it’s nested structs that are tagged for validation.

pub fn errors_mut(&mut self) -> &mut HashMap<&'static str, ValidationErrorsKind>

Returns a mutable map of field-level validation errors found for the struct that was validated and any of it’s nested structs that are tagged for validation.

pub fn into_errors(self) -> HashMap<&'static str, ValidationErrorsKind>

Consume the struct, returning the validation errors found

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

Returns a map of only field-level validation errors found for the struct that was validated.

pub fn add(&mut self, field: &'static str, error: ValidationError)

pub fn is_empty(&self) -> bool

Trait Implementations

impl Clone for ValidationErrors

fn clone(&self) -> ValidationErrors

Returns a copy 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, fmt: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for ValidationErrors

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 source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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 PartialEq for ValidationErrors

fn eq(&self, other: &ValidationErrors) -> 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 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.
