Enum BzzError 

#[non_exhaustive]
pub enum BzzError {
    TooShort,
    InvalidBlockSize,
    InvalidBwtIndex,
    ZpError,
    MissingMarker,
    BlockSizeTooLarge(usize),
    OutputTooLarge,
    Truncated,
}

BZZ compression decoding errors.

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.

TooShort

Input is too short to be a valid BZZ stream (fewer than 2 bytes).

InvalidBlockSize

The block size field in the BZZ stream is invalid or out of range.

InvalidBwtIndex

The BWT sort index embedded in the stream is out of range.

ZpError

The ZP arithmetic coder encountered an error.

MissingMarker

The BWT block did not contain an end-of-block marker.

BlockSizeTooLarge(usize)

A single block’s decoded size exceeds the safety limit (4 MB).

OutputTooLarge

The total decompressed output exceeds the safety limit (256 MB).

Truncated

The ZP coder ran past the real input and is decoding synthetic padding as if it were data (a truncated or hostile stream).

Trait Implementations

impl Debug for BzzError

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

Formats the value using the given formatter.

impl Display for BzzError

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

Formats the value using the given formatter.

impl Eq for BzzError

impl Error for BzzError

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<BzzError> for DjVuError

fn from(source: BzzError) -> Self

Converts to this type from the input type.

impl From<BzzError> for DocError

fn from(source: BzzError) -> Self

Converts to this type from the input type.

impl From<BzzError> for RenderError

fn from(source: BzzError) -> Self

Converts to this type from the input type.

impl From<ZpError> for BzzError

Map ZP-coder init errors into BzzError so callers using ? keep working.

fn from(_: ZpError) -> BzzError

Converts to this type from the input type.

impl PartialEq for BzzError

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

Equality operator ==.

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

Inequality operator !=.
