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

Fields

offset: usize

header_length: usize

Tried to access something outside of the volume header.

InvalidFilename

Fields

error: Utf8Error

The underlying error.

filename: Vec<u8>

The original filename.

A filename wasn’t valid UTF-8.

UnsupportedHeaderEntry

Fields

tag: Tag

The tag that was encountered.

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

UnknownTag

Fields

tag: u8

The raw value.

Encountered a Tag with an known value.

NotADirectory

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

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)>

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, demand: &mut Demand<'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<VolumeHeaderError> for VolumeHeaderError

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

This method tests for self and other values to be equal, and is used by ==.

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

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