Struct ErrorInfo 

#[non_exhaustive]
pub struct ErrorInfo {
    pub code: String,
    pub message: String,
    pub path: Option<String>,
    pub workflow_id: Option<String>,
    pub task_id: Option<String>,
    pub timestamp: Option<String>,
    pub retry_attempted: Option<bool>,
    pub retry_count: Option<u32>,
    pub detail: Option<String>,
}

Structured error information for error tracking in messages

#[non_exhaustive]: construct through ErrorInfo::builder, ErrorInfo::new, ErrorInfo::simple or ErrorInfo::simple_ref, which are the documented paths. Field reads and .. patterns are unaffected, and future field additions stay non-breaking.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

code: String

Error code (e.g., “WORKFLOW_ERROR”, “TASK_ERROR”, “VALIDATION_ERROR”)

message: String

Human-readable error message

path: Option<String>

Optional path to the error location (e.g., “workflow.id”, “task.id”, “data.field”)

workflow_id: Option<String>

ID of the workflow where the error occurred (if available)

task_id: Option<String>

ID of the task where the error occurred (if available)

timestamp: Option<String>

Timestamp when the error occurred

retry_attempted: Option<bool>

Whether a retry was attempted

retry_count: Option<u32>

Number of retries attempted

detail: Option<String>

Operator-only detail lifted from DataflowError::Service.

Present on the persisted trace; a service must not surface it to an untrusted caller. None for every engine-owned error, and omitted from the serialized form when absent, so the JSON shape is unchanged unless a Service error carried one.

Implementations

impl ErrorInfo

pub fn new( workflow_id: Option<String>, task_id: Option<String>, error: DataflowError, ) -> Self

Create a new error info entry with all fields

pub fn simple(code: String, message: String, path: Option<String>) -> Self

Create a simple error info with just code, message, and optional path

pub fn simple_ref(code: &str, message: &str, path: Option<&str>) -> Self

Create a simple error info from references (avoids cloning when possible)

pub fn with_retry(self) -> Self

Mark that a retry was attempted

pub fn builder( code: impl Into<String>, message: impl Into<String>, ) -> ErrorInfoBuilder

Create a builder for ErrorInfo
