Struct UdbError 

pub struct UdbError {
    pub status: Status,
    pub detail: Option<ErrorDetail>,
}

A Status plus the broker’s structured detail, when it sent one.

Fields

status: Status

detail: Option<ErrorDetail>

Implementations

impl UdbError

pub fn from_status(status: Status) -> Self

Decode the trailer, if present and well-formed.

A malformed trailer is treated as absent rather than as a new failure: the call already failed and the caller needs the original status, not a decoding complaint layered over it.

pub fn code(&self) -> Code

pub fn message(&self) -> &str

pub fn is_retryable(&self) -> bool

Whether the BROKER said this is retryable.

Trusted over any code-based guess: the broker knows whether it got far enough to have side effects, and a client cannot infer that from UNAVAILABLE alone.

pub fn retry_after(&self) -> Option<Duration>

How long the broker asked us to wait, if it said.

pub fn capability_required(&self) -> Option<&str>

The capability the deployment is missing, for a capability refusal.

pub fn correlation_id(&self) -> Option<&str>

The correlation id to quote in a bug report or a support ticket.

pub fn field_violations(&self) -> &[ErrorFieldViolation]

Per-field rejections, for a validation failure.

Trait Implementations

impl Clone for UdbError

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.
