}

Errors returned by crate::Gate::check.

Validation(GateValidationError)

Implementations

impl GateError

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

Stable, caller-safe classification of this error’s failure category.

This is what a Gate::check caller is permitted to forward to an untrusted requester. It never includes this error’s Display text: a gate backend’s error message can embed connection details, addresses, or credentials, and that text must stay in server-side logs only (log the full error separately with its Display impl).

Internal is a transient backend-availability failure — safe to retry. Policy and Validation are non-transient: the gate backend is reachable but the request or its configured policy cannot be evaluated, and retrying the identical request will not change the outcome.

Trait Implementations

impl Debug for GateError

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

Formats the value using the given formatter.

impl Display for GateError

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

Formats the value using the given formatter.

impl Error for GateError

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<GateValidationError> for GateError

fn from(source: GateValidationError) -> Self

Converts to this type from the input type.
