Error returned while opening or decoding a CDB dictionary.

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.

Open

Opening a CDB dictionary file failed.

Fields

path: String

Path that failed to open.

source: Error

Underlying I/O error.

MissingRecord

A required record is missing.

Fields

record: &'static str

Human-readable record name.

MetadataDecode

CBOR metadata could not be decoded.

Fields

source: Error<Error>

Underlying CBOR decode error.

UnsupportedVersion

The metadata version is not supported.

Fields

version: String

Version string read from metadata.

MalformedRecord

A CDB value did not match the expected record layout.

Fields

reason: &'static str

Description of the malformed record condition.

ValueOverflow

A CDB value range overflowed while decoding.

Fields

field: &'static str

Field that overflowed.

ValueOutOfBounds

A CDB value range points outside the record.

Fields

field: &'static str

Field that was out of bounds.

InvalidUtf8

A UTF-8 string field was invalid.

Fields

field: &'static str

Field that contained invalid UTF-8.

source: Utf8Error

Underlying UTF-8 error.

TooShort

The CDB data is shorter than the required 2048-byte header.

Fields

len: usize

Actual byte length of the data.

OutOfBounds

A CDB header slot or record points outside the data buffer.

Fields

offset: usize

The out-of-bounds offset.

len: usize

The data length.

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.
