Validation errors occurring during rule evaluation

FunctionExecution

Errors during function execution

Fields

context: String

source: Option<Box<DataflowError>>

Workflow(String)

Workflow-related errors

Task(String)

Task-related errors

FunctionNotFound(String)

Function not found errors

Deserialization(String)

JSON serialization/deserialization errors

Io(String)

I/O errors (file reading, etc.)

LogicEvaluation(String)

JSONLogic/DataLogic evaluation errors

Http

HTTP request errors

Fields

status: u16

message: String

Timeout(String)

Timeout errors

Unknown(String)

Any other errors

Implementations

impl DataflowError

pub fn function_execution<S: Into<String>>( context: S, source: Option<DataflowError>, ) -> Self

Creates a new function execution error with context

pub fn http<S: Into<String>>(status: u16, message: S) -> Self

Creates a new HTTP error

pub fn from_io(err: Error) -> Self

Convert from std::io::Error

pub fn from_serde(err: Error) -> Self

Convert from serde_json::Error

pub fn retryable(&self) -> bool

Determines if this error is retryable (worth retrying)

Retryable errors are typically transient infrastructure failures that might succeed on retry. Non-retryable errors are typically data validation, logic, or configuration errors that will consistently fail on retry.

Trait Implementations

impl Clone for DataflowError

fn clone(&self) -> DataflowError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataflowError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DataflowError

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DataflowError

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

Formats the value using the given formatter.

impl Error for DataflowError

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 Serialize for DataflowError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
