Enum HeaderError

pub enum HeaderError {
    InvalidSignature,
    UnsupportedVersion,
    InvalidBlockSize,
}

An error returned by Header

Variants

InvalidSignature

The file signature isn’t valid (should be BZ)

UnsupportedVersion

The bzip2 version isn’t supported (only the huffman version is supported)

InvalidBlockSize

The blocksize isn’t 1..=9

Trait Implementations

impl Clone for HeaderError

fn clone(&self) -> HeaderError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeaderError

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

Formats the value using the given formatter.

impl Display for HeaderError

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

Formats the value using the given formatter.

impl Error for HeaderError

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<HeaderError> for DecoderError

fn from(err: HeaderError) -> Self

Converts to this type from the input type.

impl From<HeaderError> for Error

fn from(err: HeaderError) -> Error

Converts to this type from the input type.

impl PartialEq for HeaderError

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