Validation errors for Celery protocol messages

Examples

use celers_protocol::{Message, ValidationError};
use uuid::Uuid;

// Create a message with an empty task name
let msg = Message::new("".to_string(), Uuid::new_v4(), vec![1, 2, 3]);

// Validation will fail with a structured error
match msg.validate() {
    Ok(_) => panic!("Should have failed"),
    Err(ValidationError::EmptyTaskName) => {
        println!("Task name cannot be empty");
    }
    Err(e) => panic!("Unexpected error: {}", e),
}

Fields

mode: u8

InvalidPriority

Invalid priority (must be 0-9)

Fields

priority: u8

EmptyContentType

Content type is empty

EmptyBody

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> ValidationError

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 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 BuilderError

fn from(err: ValidationError) -> Self

Converts to this type from the input type.

impl From<ValidationError> for ExtensionError

fn from(err: ValidationError) -> Self

Converts to this type from the input type.

impl From<ValidationError> for MiddlewareError

fn from(err: ValidationError) -> Self

Converts to this type from the input type.

impl Hash for ValidationError

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 PartialEq for ValidationError

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