Errors that can occur when opening a KeePass 1 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.

InvalidFieldLength

A field has an invalid length (either too short or too long) compared to the expected length for its type

Fields

field_type: u16

The type of the field that has an invalid length

field_size: u32

The actual length of the field as read from the database

expected_field_size: u32

The expected length of the field based on its type, if it is a known fixed-length type

InvalidGroupLevel

A group has an invalid level that does not match the expected level based on the current depth of the group tree being parsed

Fields

current: Option<u16>

The actual level of the group as read from the database, or None if the level field was missing

expected: u16

The expected level of the group based on the current depth of the group tree being parsed

InvalidGroupId(Option<u32>)

Encountered the end of a group definition without finding a valid group ID field, or found a group ID that does not match any previously defined group

InvalidGroupFieldType(u16)

Encountered a field type in a group definition that is not recognized as a valid group field type

IncompleteGroup

Encountered the end of the file before the current group definition was properly terminated with an end-of-group field

EntryMissingGroupId

Encountered an entry definition that is missing a valid group ID field

InvalidEntryFieldType(u16)

Encountered an invalid entry field type

IncompleteEntry

Encountered the end of the file before the current entry definition was properly terminated

InvalidFixedCipherID(u32)

The database is encrypted with a cipher that is not recognized or supported

Trait Implementations

impl Debug for KdbOpenError

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

Formats the value using the given formatter.

impl Display for KdbOpenError

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

Formats the value using the given formatter.

impl Error for KdbOpenError

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<KdbOpenError> for DatabaseFormatError

fn from(source: KdbOpenError) -> Self

Converts to this type from the input type.
