Top-level error type for epub-stream operations

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.

Phase(PhaseError)

Typed phase-aware error with structured context.

Zip(ZipError)

ZIP archive error

Parse(String)

XML/XHTML parsing error

InvalidEpub(String)

Invalid EPUB structure (missing required files, broken references, etc.)

Navigation(String)

Navigation parsing error

Css(String)

CSS parsing error

Io(String)

I/O error (description only, since std::io::Error is not Clone)

ChapterOutOfBounds

Chapter index requested is out of bounds

Fields

index: usize

Requested chapter index.

chapter_count: usize

Total number of chapters available.

ManifestItemMissing

Spine references a manifest item that does not exist

Fields

idref: String

Missing manifest id referenced by spine idref.

ChapterNotUtf8

Chapter content could not be decoded as UTF-8

Fields

href: String

Chapter href/path in the EPUB archive.

LimitExceeded

Hard limit exceeded (typed error instead of OOM)

Fields

kind: LimitKind

Kind of limit that was exceeded.

actual: usize

Actual value observed.

limit: usize

Configured limit.

path: Option<String>

Optional path context.

BufferTooSmall

Provided buffer is too small for the operation

Fields

required: usize

Required size.

provided: usize

Provided size.

context: String

Context about which buffer.

Trait Implementations

impl Clone for EpubError

fn clone(&self) -> EpubError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpubError

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

Formats the value using the given formatter.

impl Display for EpubError

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

Formats the value using the given formatter.

impl Error for EpubError

Available on crate feature std only.

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<PhaseError> for EpubError

fn from(err: PhaseError) -> Self

Converts to this type from the input type.

impl From<RenderPrepError> for EpubError

fn from(err: RenderPrepError) -> Self

Converts to this type from the input type.

impl From<TokenizeError> for EpubError

fn from(err: TokenizeError) -> Self

Converts to this type from the input type.

impl PartialEq for EpubError

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