Available on crate feature v3 only.

Errors that may occur while reading a volume header.

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.

NotFound

The item wasn’t found.

AccessOutOfBounds

Tried to access something outside of the volume header.

Fields

offset: usize

header_length: usize

InvalidFilename

A filename wasn’t valid UTF-8.

Fields

error: Utf8Error

The underlying error.

filename: Vec<u8>

The original filename.

UnsupportedHeaderEntry

Encountered an entry with a tag that isn’t supported.

Fields

tag: Tag

The tag that was encountered.

UnknownTag

Encountered a Tag with an known value.

Fields

tag: u8

The raw value.

NotADirectory

Found a directory when one wasn’t expected (e.g. when looking up a file’s data).

InvalidTime

Fields

duration: Duration

Trait Implementations

impl Clone for VolumeHeaderError

fn clone(&self) -> VolumeHeaderError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VolumeHeaderError

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

Formats the value using the given formatter.

impl Display for VolumeHeaderError

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

Formats the value using the given formatter.

impl Error for VolumeHeaderError

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<VolumeHeaderError> for DirEntryError

fn from(source: VolumeHeaderError) -> Self

Converts to this type from the input type.

impl From<VolumeHeaderError> for LookupError

fn from(source: VolumeHeaderError) -> Self

Converts to this type from the input type.

impl PartialEq for VolumeHeaderError

fn eq(&self, other: &VolumeHeaderError) -> 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.
