Variants

Auth

Authentication failure. reason is "expired", "invalid", or "missing".

Fields

reason: String

AccessDenied

Caller lacks permission for op on resource.

Fields

op: String

resource: String

NotFound

The requested resource does not exist.

Fields

resource: String

Conflict

ETag precondition failure.

Fields

etag_expected: String

etag_actual: Option<String>

RateLimited

AWS / provider rate-limit hit. retry_after_ms is the hint from the Retry-After header when present.

Fields

retry_after_ms: Option<u64>

Unsupported

The requested operation is not supported by this provider.

Fields

op: String

provider: String

Network

Network-level failure. source is the stringified upstream error.

Fields

source: String

Cancelled

User-initiated cancellation. Not retryable.

Locked

A resource is held by an active lock.

Fields

lock_id: String

op_name: String

Validation

Input validation failure.

Fields

field: String

hint: String

ProviderSpecific

Provider-specific error not mappable to another variant.

Fields

code: String

message: String

Internal

Catch-all. trace_id ties this error to the diagnostics log bundle.

Fields

trace_id: String

Implementations

impl AppError

pub fn internal_new() -> Self

Construct an Internal error with a freshly-minted UUID v4 trace id.

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

The kind string used in the IPC envelope.

pub fn retryable(&self) -> bool

Whether the frontend should offer a retry action.

pub fn message(&self) -> String

Human-readable summary for the message field of the IPC envelope.

fn details(&self) -> Option<Value>

Variant payload as a JSON Value, or None for Cancelled.

Trait Implementations

impl Clone for AppError

fn clone(&self) -> AppError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AppError

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

Formats the value using the given formatter.

impl Display for AppError

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

Formats the value using the given formatter.

impl Error for AppError

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 Serialize for AppError

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
