Struct opendal::Error

pub struct Error { /* private fields */ }

Error is the error struct returned by all opendal functions.

Implementations

impl Error

pub fn new(kind: ErrorKind, message: &str) -> Self

Create a new Error with error kind and message.

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

Update error’s operation.

Notes

If the error already carries an operation, we will push a new context (called, operation).

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

Add more context in error.

pub fn set_source(self, src: impl Into<Error>) -> Self

Set source for error.

Notes

If the source has been set, we will raise a panic here.

pub fn map<F>(self, f: F) -> Selfwhere F: FnOnce(Self) -> Self,

Operate on error with map.

pub fn set_permanent(self) -> Self

Set permanent status for error.

pub fn set_temporary(self) -> Self

Set temporary status for error.

By set temporary, we indicate this error is retryable.

pub fn set_persistent(self) -> Self

Set persistent status for error.

By setting persistent, we indicate the retry should be stopped.

pub fn kind(&self) -> ErrorKind

Return error’s kind.

pub fn is_temporary(&self) -> bool

Check if this error is temporary.

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 Error + 'static)>

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
