Struct Rejection 

pub struct Rejection {
    pub reason_key: &'static str,
    pub message: Option<Cow<'static, str>>,
}

A structured validator rejection captured during typed rehydration.

Fields

reason_key: &'static str

Stable machine-readable reason key for why the validator rejected.

message: Option<Cow<'static, str>>

Optional human-readable message for debugging and reports.

Implementations

impl Rejection

pub const fn new(reason_key: &'static str) -> Self

Create a rejection with a stable reason key and no message.

pub fn with_message(self, message: impl Into<Cow<'static, str>>) -> Self

Attach a human-readable message to this rejection.

Trait Implementations

impl Clone for Rejection

fn clone(&self) -> Rejection

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Rejection

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

Formats the value using the given formatter.

impl Display for Rejection

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

Formats the value using the given formatter.

impl Error for Rejection

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<&'static str> for Rejection

fn from(reason_key: &'static str) -> Self

Converts to this type from the input type.

impl PartialEq for Rejection

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