Implementations

impl DejaDbError

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

Stable machine-readable error code in DOMAIN-Ennn form (see the repo-root ERROR_CODES.md registry). Every Display string begins with this code, so a user who reports the leading token points us at the exact variant and subsystem. Codes are append-only debugging handles — never renumber or reuse an existing one.

Trait Implementations

impl Debug for DejaDbError

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

Formats the value using the given formatter.

impl Display for DejaDbError

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

Formats the value using the given formatter.

impl Error for DejaDbError

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.
