Struct Errors

pub struct Errors<T>
where
    T: Debug + Any,
{ /* private fields */ }

A collection of errors returned by a failed validation.

Implementations

impl<T> Errors<T>

where T: Debug + Any,

pub fn new() -> Self

Constructs an empty Errors value.

pub fn add_error(&mut self, error: Error<T>)

Adds a validation error that is not specific to any field.

pub fn add_field_error<S>(&mut self, field: S, error: Error<T>)

where S: Into<String>,

Adds a validation error for the given field.

Calling this method will overwrite any errors assigned via set_field_errors.

pub fn base<'a>(&'a self) -> Option<&'a [Error<T>]>

A slice of non-field-specific errors, if any.

pub fn field<F>(&self, field: F) -> Option<&Box<Errors<T>>>

where F: Into<String>,

The Errors for the given field, if any.

pub fn is_empty(&self) -> bool

Returns true if there are no errors.

pub fn set_field_errors<S>(&mut self, field: S, errors: Errors<T>)

where S: Into<String>,

Sets the given field’s errors to the given Errors.

This is useful if the field itself implements Validate. In that case, the parent type can simply delegate to the field to validate itself and assign the resulting errors using this method.

Calling this method will overwrite any field errors previously added with add_field_error.

Trait Implementations

impl<T> Debug for Errors<T>

where T: Debug + Any + Debug,

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

Formats the value using the given formatter.

impl<T> Display for Errors<T>

where T: Debug + Any,

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

Formats the value using the given formatter.

impl<T> Error for Errors<T>

where T: Debug + Any,

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

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

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.
