Stable wire error codes; errors never contain credentials or application data.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnsupportedVersion

An unsupported protocol input was presented.

InvalidFrame

The JSON frame is malformed.

InvalidRequest

An identifier or operation violates the contract.

PayloadTooLarge

Encoded or decoded data exceeds the selected budget.

IdempotencyRequired

A command omitted its validated idempotency key.

IdempotencyPending

An equivalent command is still executing or requires effect reconciliation.

IdempotencyConflict

A key was reused for a semantically different operation.

AuthenticationRequired

A valid authenticated principal is required.

Forbidden

The owning authorization policy denies this operation.

Busy

Admission or subscription capacity is exhausted.

Unavailable

The selected transport/backend is unavailable.

Cancelled

Cooperative cancellation was requested.

DeadlineExceeded

The monotonic execution budget elapsed.

Closed

The surface no longer admits operations.

SubscriptionNotFound

A subscription no longer exists in this surface generation.

SequenceExhausted

A sequence cannot safely advance without identity reuse.

BackendFailure

An owning backend failed; its raw detail remains outside the wire response.

Trait Implementations

impl Clone for UiError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for UiError

impl Debug for UiError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UiError

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

where __D: Deserializer<'de>,

impl Eq for UiError

impl Error for UiError

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 PartialEq for UiError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for UiError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
