Trait Implementations

impl Debug for TraitBasedError

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

Formats the value using the given formatter.

impl Display for TraitBasedError

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

Formats the value using the given formatter.

impl Error for TraitBasedError

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.

impl ErrorCategory for TraitBasedError

fn category(&self) -> ErrorCategoryType

fn severity(&self) -> ErrorSeverity

impl ErrorContextProvider for TraitBasedError

fn file(&self) -> Option<&str>

fn row(&self) -> Option<usize>

fn column(&self) -> Option<usize>

fn cell_ref(&self) -> Option<&str>

fn column_name(&self) -> Option<&str>

impl RecoverableError for TraitBasedError

fn can_recover(&self) -> bool

fn recovery_action(&self) -> Option<String>

impl UserFriendlyError for TraitBasedError

fn user_message(&self) -> String
