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.

impl From<Error> for Error

Converts LMDB-specific errors (lmdb::Error) into the database interface Error type.

This implementation maps LMDB errors to a meaningful representation in the library context, allowing better handling of database errors.

Notes:

• The NotFound error is deliberately not converted to the custom Error type because it is represented by the Option type in the interface itself.
• For errors like Other, additional contextual information is included for debugging purposes.

fn from(value: Error) -> Error

Converts to this type from the input type.
