Struct ValidationError 

pub struct ValidationError {
    pub path: String,
    pub kind: ValidationKind,
    pub actual: Option<ValidationMeasure>,
    pub limit: Option<ValidationMeasure>,
}

Typed validation failure for a wire payload.

path is a JSON-like field path (tempo, spikes, traces[1].channel_id). actual / limit identify the observed value or size and the applicable bound when those are meaningful for kind.

Fields

path: String

Field or indexed path that failed.

kind: ValidationKind

Stable error kind.

actual: Option<ValidationMeasure>

Observed value, count, or byte length when applicable.

limit: Option<ValidationMeasure>

Applicable limit or documented range.

Implementations

impl ValidationError

pub fn non_finite(path: impl Into<String>, actual: f32) -> Self

Non-finite float at path.

pub fn out_of_range( path: impl Into<String>, actual: f32, min: f32, max: f32, ) -> Self

Float outside [min, max] at path.

pub fn length_mismatch( path: impl Into<String>, actual: usize, expected: usize, ) -> Self

Related sequences had different lengths.

pub fn limit_exceeded( path: impl Into<String>, actual: usize, limit: usize, ) -> Self

Collection length exceeded limit.

pub fn byte_limit(path: impl Into<String>, actual: usize, limit: usize) -> Self

String byte length exceeded limit.

pub fn nested_metadata(path: impl Into<String>) -> Self

Nested metadata policy violation (for example an empty key).

pub fn duplicate_identifier( path: impl Into<String>, identifier: impl Display, ) -> Self

Duplicate identifier at path.

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Eq for ValidationError

impl Error for ValidationError

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<ValidationError> for CanonicalEncodeError

fn from(source: ValidationError) -> Self

Converts to this type from the input type.

impl From<ValidationError> for ZmqMessageError

fn from(source: ValidationError) -> Self

Converts to this type from the input type.

impl PartialEq for ValidationError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
