}

Error variants for goal store operations.

Variants

NotFound(String)

The requested goal ID does not exist in the store.

InvalidTransition

The requested FSM transition is not permitted from the current status.

Fields

from: GoalStatus

to: GoalStatus

StaleUpdate(String)

The CAS-guarded update was rejected because expected_updated_at did not match.

BudgetExceeded

The goal has consumed more tokens than its configured budget allows.

Fields

used: u64

budget: u64

TextTooLong

The provided goal text exceeds the maximum allowed character length.

Fields

max: usize

InvalidText

The goal text contains content that would break system-prompt XML structure.

Db(SqlxError)

A database error occurred during the operation.

Trait Implementations

impl Debug for GoalError

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

Formats the value using the given formatter.

impl Display for GoalError

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

Formats the value using the given formatter.

impl Error for GoalError

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 GoalError

fn from(source: SqlxError) -> Self

Converts to this type from the input type.
