Struct Error 

pub struct Error { /* private fields */ }

A cudf error. See the module-level docs for the contract.

Implementations

impl Error

pub fn code(&self) -> ErrorCode

The stable machine-readable failure identity.

pub fn kind(&self) -> ErrorKind

The coarse failure category (pure projection of code).

pub fn status(&self) -> ErrorStatus

The retry semantic (pure projection of code).

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

The cudf boundary at which this error was surfaced.

pub fn message(&self) -> &str

The one-line primary failure description.

pub fn facts(&self) -> &Facts

Canonical typed facts.

pub fn fact_value(&self, key: FactKeyName) -> Option<&FactValue>

The value of a canonical fact, if present.

pub fn details(&self) -> &[(&'static str, String)]

Open-ended diagnostic annotations (may contain repeated keys).

pub fn detail_value(&self, key: &str) -> Option<&str>

The first detail value recorded for key, if any.

pub fn detail_values<'a>( &'a self, key: &'a str, ) -> impl Iterator<Item = &'a str> + 'a

All detail values recorded for key, in insertion order.

pub fn budget_exhaustion(&self) -> Option<&BudgetExhaustionDetail>

Typed budget-exhaustion counters attached by a hard budget token.

pub fn ffi_detail(&self) -> Option<&CudfErrorDetail>

The native shim payload copied at the failed FFI boundary, if present.

pub fn call_chain(&self) -> &[&'static str]

Ordered trail of prior primary operations this error has been re-anchored from. No deduplication.

pub fn source_error(&self) -> Option<&(dyn StdError + 'static)>

Underlying error cause, if any.

pub fn diagnostic_string(&self) -> String

Stable diagnostic string for logs and query-engine adapters.

This formats the existing error contract without introducing parallel stored kind/status fields or string-only categories. Callers that need policy decisions should keep using code, kind, status, and facts directly.

pub fn is_retryable(&self) -> bool

Equivalent to status() == Temporary.

pub fn is_temporary(&self) -> bool

Equivalent to status() == Temporary.

pub fn is_permanent(&self) -> bool

Equivalent to status() == Permanent.

pub fn is_persistent(&self) -> bool

Equivalent to status() == Persistent.

pub fn is_oom(&self) -> bool

Equivalent to code() == ErrorCode::OutOfMemory.

This is the single domestic OOM leaf. Foreign resource exhaustion is a different leaf and does not alias here.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn StdError + '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 DeviceMemoryManagerInstallationError

fn from(error: Error) -> Self

Converts to this type from the input type.
