Struct Error 

pub struct Error { /* private fields */ }

Implementations

impl Error

pub fn new(kind: ErrorKind, operation: &'static str) -> Self

pub fn with_message(self, message: impl Into<String>) -> Self

pub fn with_operation(self, operation: &'static str) -> Self

pub fn with_context(self, key: &'static str, value: impl ToString) -> Self

pub fn set_source<E>(self, source: E) -> Self

where E: StdError + Send + Sync + 'static,

pub fn set_temporary(self) -> Self

pub fn set_permanent(self) -> Self

pub fn set_persistent(self) -> Self

pub fn kind(&self) -> ErrorKind

pub fn status(&self) -> ErrorStatus

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

pub fn message(&self) -> &str

pub fn context(&self) -> impl ExactSizeIterator<Item = (&'static str, &str)>

Structured diagnostic facts forwarded from cudf/interop/native error contracts. Consumers must not parse message or Display to classify an error.

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

pub fn is_temporary(&self) -> bool

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.
