Enum ErrorDomain 

pub enum ErrorDomain {
    Planning,
    Reflection,
    Action,
    System,
}

High-level error domain for recovery strategy dispatch.

Groups the ToolErrorCategory variants into 4 domains that map to distinct recovery strategies in the agent loop. Does NOT replace ToolErrorCategory — it is a companion abstraction for coarse dispatch.

Examples

use zeph_common::error_taxonomy::ErrorDomain;

assert!(ErrorDomain::System.is_auto_retryable());
assert!(!ErrorDomain::Planning.is_auto_retryable());

Variants

Planning

The agent selected the wrong tool or misunderstood the task. Recovery: re-plan, pick a different tool or approach. Categories: ToolNotFound

Reflection

The agent’s output (parameters, types) was malformed. Recovery: reformat parameters using tool schema, retry once. Categories: InvalidParameters, TypeMismatch

Action

External action failed due to policy or resource constraints. Recovery: inform user, suggest alternative, or skip. Categories: PolicyBlocked, ConfirmationRequired, PermanentFailure, Cancelled

System

Transient infrastructure failure. Recovery: automatic retry with backoff. Categories: RateLimited, ServerError, NetworkError, Timeout

Implementations

impl ErrorDomain

pub fn is_auto_retryable(self) -> bool

Whether errors in this domain should trigger automatic retry.

pub fn needs_llm_correction(self) -> bool

Whether the LLM should be asked to fix its output.

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

Human-readable label for audit logs.

Trait Implementations

impl Clone for ErrorDomain

fn clone(&self) -> ErrorDomain

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorDomain

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ErrorDomain

fn deserialize<__D>( __deserializer: __D, ) -> Result<ErrorDomain, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ErrorDomain

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 ErrorDomain

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ErrorDomain
