Struct ValidationErrors 

pub struct ValidationErrors { /* private fields */ }

Holds the rich context concerning the validation errors that occur during validation.

Can be converted into Violations to be serialized into protobuf.

When the feature tonic is enabled, it can be converted directly into tonic::Status so that the ? operator can be used directly inside tonic handlers.

Implementations

impl ValidationErrors

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

Appends the contents of another ValidationErrors to the original instance.

pub fn iter(&self) -> Iter<'_>

Returns a ref iterator.

pub fn iter_mut(&mut self) -> IterMut<'_>

Returns a mutable ref iterator.

pub fn retain<F>(&mut self, f: F)

where F: FnMut(ViolationCtxRef<'_>) -> bool,

Removes the violations that match the given predicate.

pub const fn new() -> Self

Creates a new instance.

pub fn into_status(self) -> Status

Turns into Status, the equivalent of the google.rpc.Status message.

pub fn into_violations(self) -> Violations

Converts into Violations.

pub fn push(&mut self, v: ViolationCtx)

Adds a new violation to the list.

pub const fn is_empty(&self) -> bool

Checks if this instance contains any violations.

pub const fn len(&self) -> usize

Returns the amount of violations contained.

Trait Implementations

Available on crate feature tonic only.

fn from(value: ValidationErrors) -> Self

Converts to this type from the input type.

impl From<ValidationErrors> for Status

fn from(value: ValidationErrors) -> Self

Converts to this type from the input type.

impl From<ValidationErrors> for Vec<Violation>

fn from(value: ValidationErrors) -> Self

Converts to this type from the input type.

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> IntoIterator for &'a ValidationErrors

type Item = ViolationCtxRef<'a>

The type of the elements being iterated over.

type IntoIter = Iter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a> IntoIterator for &'a mut ValidationErrors

type Item = ViolationCtxMut<'a>

The type of the elements being iterated over.

type IntoIter = IterMut<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for ValidationErrors

type IntoIter = IntoIter

Which kind of iterator are we turning this into?

type Item = ViolationCtx

The type of the elements being iterated over.

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

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.
