Enum DatabaseOpenError 

#[non_exhaustive]
pub enum DatabaseOpenError {

Errors that can occur when opening a database

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Error)

I/O errors that can occur while reading the database from the source

UnexpectedEof

An unexpected end of file was encountered while reading the database

VersionParse(DatabaseVersionParseError)

Errors related to parsing the database version from the file header

UnsupportedVersion

Attempted to open a database with an unsupported version

Key(DatabaseKeyError)

Errors related to the database key, such as incorrect keys

Cryptography(CryptographyError)

Errors related to decryption

Format(DatabaseFormatError)

Errors related to parsing the database format

Trait Implementations

impl Debug for DatabaseOpenError

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

Formats the value using the given formatter.

impl Display for DatabaseOpenError

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

Formats the value using the given formatter.

impl Error for DatabaseOpenError

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.
