Enum ProcessError 

pub enum ProcessError {
    InvalidInput(String),
    Unavailable(String),
    Internal(String),
    DeadlineExceeded,
    Fatal(String),
}

Rust mapping of the WIT process-error variant.

This type has exactly 5 variants matching the WIT definition in torvyn:streaming@0.1.0 (Doc 01, Section 3.1). It is the error type returned by component invocations (process, pull, push).

Variants

• InvalidInput — input element was malformed or violated the contract.
• Unavailable — a required resource or service was unavailable.
• Internal — unexpected internal error within the component.
• DeadlineExceeded — the processing deadline has passed.
• Fatal — the component is permanently unable to process further elements.

Examples

use torvyn_types::ProcessError;

let err = ProcessError::InvalidInput("expected JSON, got binary".into());
assert!(format!("{}", err).contains("expected JSON"));

Variants

InvalidInput(String)

The input element was malformed or violated the expected contract.

Unavailable(String)

A resource or service required by the component was unavailable.

Internal(String)

An unexpected internal error occurred within the component.

DeadlineExceeded

The component’s processing deadline has been exceeded.

Fatal(String)

The component is permanently unable to process further elements. This is a terminal error — the runtime will not send more elements.

Implementations

impl ProcessError

pub fn is_fatal(&self) -> bool

Returns true if this is a terminal error (the component should be removed).

HOT PATH — called per error to determine flow control action.

pub fn kind(&self) -> &'static str

Returns the error kind as a static string for metrics and logging.

HOT PATH — called for observability categorization.

Trait Implementations

impl Clone for ProcessError

fn clone(&self) -> ProcessError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProcessError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProcessError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ProcessError

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

Formats the value using the given formatter.

impl Error for ProcessError

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<&ProcessError> for ProcessErrorKind

fn from(err: &ProcessError) -> Self

Converts to this type from the input type.

impl From<ProcessError> for TorvynError

fn from(e: ProcessError) -> Self

Converts to this type from the input type.

impl PartialEq for ProcessError

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

impl Serialize for ProcessError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ProcessError
