Struct ErrorSource 

pub struct ErrorSource {
    pub task: Option<String>,
    pub agent: Option<String>,
    pub provider: Option<String>,
    pub model: Option<String>,
    pub tool_ref: Option<String>,
    pub script: Option<String>,
    pub line: Option<u32>,
}

Where in the workflow an error originated. Every field is optional — fill what you know, leave the rest. SDKs render whichever fields are present; downstream tools (logs, OTel) read them as structured attributes for filtering/aggregation.

Fields

task: Option<String>

Workflow-author-declared task name (matches task <name> in source).

agent: Option<String>

Agent name from the matching agent <name> declaration.

provider: Option<String>

Provider id when the error came from an LLM/provider call (anthropic, google, openai, …).

model: Option<String>

Model alias (opus_4_7, gpt_4o_mini, …).

tool_ref: Option<String>

MCP <alias>.<tool> reference when the error came from a tool call.

script: Option<String>

Script name when the error came from a sub-script (call(...)).

line: Option<u32>

1-indexed source line in the originating .akr file.

Trait Implementations

impl Clone for ErrorSource

fn clone(&self) -> ErrorSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorSource

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

Formats the value using the given formatter.

impl Default for ErrorSource

fn default() -> ErrorSource

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ErrorSource

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ErrorSource

fn eq(&self, other: &ErrorSource) -> 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 ErrorSource

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
