Enum CoreError 

pub enum CoreError {
    Tool(String),
    Memory(String),
    Governance(String),
    RateLimited(String),
    CircuitBreaker(String),
    InvalidArgs(String),
    NotFound(String),
    Polyglot(String),
    Io(Error),
    Serde(Error),

}

Core error type covering all WhiteMagic failure modes.

Variants

Tool(String)

Tool execution failed

Memory(String)

Memory operation failed

Governance(String)

Governance rule violation

RateLimited(String)

Rate limit exceeded

CircuitBreaker(String)

Circuit breaker open

InvalidArgs(String)

Invalid arguments

NotFound(String)

Resource not found

Polyglot(String)

Polyglot bridge error

Io(Error)

I/O error

Serde(Error)

Serialization error

Internal(String)

Internal error (should not happen in normal operation)

Implementations

impl CoreError

pub const fn is_retryable(&self) -> bool

Whether this error is retryable.

pub const fn is_governance(&self) -> bool

Whether this error indicates a governance violation.

pub const fn counts_as_breaker_failure(&self) -> bool

Whether this error should count against a tool’s circuit breaker.

Caller-caused failures (invalid arguments, governance refusals, not-found lookups, rate limiting) say nothing about backend health. Counting them let a handful of bad requests trip a breaker and block VALID requests that followed (2026-09-15 audit: five invalid-galaxy creates fast-failed the next correct call).

Trait Implementations

impl Debug for CoreError

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

Formats the value using the given formatter.

impl Display for CoreError

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

Formats the value using the given formatter.

impl Error for CoreError

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<Error> for CoreError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for CoreError

fn from(source: Error) -> Self
