Errors returned while parsing a .DS_Store put-back store.

Variants

TruncatedHeader

The file is shorter than the 36-byte Bud1 header.

Fields

got: usize

Bytes present.

needed: usize

Bytes required.

BadMagic

The leading 00 00 00 01 / Bud1 magic is wrong. Carries the offending bytes for the investigator.

Fields

word0: u32

The first 32-bit big-endian word (expected 1).

magic: [u8; 4]

The 4 magic bytes (expected Bud1).

RootOffsetMismatch

The two copies of the root-block offset in the header disagree — the allocator is inconsistent (Finder rejects such files).

Fields

first: u32

The first root-block offset.

second: u32

The second (validation) copy.

OutOfBounds

A block address points outside the file, or a structure overruns its block. Carries the operation for diagnosis.

Fields

what: &'static str

What was being read when the bound was exceeded.

NoDsdb

The allocator’s table of contents has no DSDB B-tree entry.

UnknownDataType

A record carried a .DS_Store data-type code the format does not define, so the record stream cannot be safely advanced. Carries the bytes.

Fields

typecode: [u8; 4]

The offending 4-byte data-type code.

Trait Implementations

impl Debug for DsStoreError

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

Formats the value using the given formatter.

impl Display for DsStoreError

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

Formats the value using the given formatter.

impl Eq for DsStoreError

impl Error for DsStoreError

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 PartialEq for DsStoreError

fn eq(&self, other: &DsStoreError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
