Implementations

impl Error

pub fn is_recoverable(&self) -> bool

Check if this error is recoverable

Recoverable errors can typically be retried or worked around. Non-recoverable errors indicate serious problems that require user intervention.

pub fn user_message(&self) -> String

Get a user-friendly error message with troubleshooting hints

pub fn is_corruption(&self) -> bool

Check if this is a corruption-related error

pub fn is_version_error(&self) -> bool

Check if this is a version-related error

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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.
