Struct flate2::DecompressError

pub struct DecompressError(_);

Error returned when a decompression object finds that the input stream of bytes was not a valid input stream of bytes.

Implementations

impl DecompressError

pub fn needs_dictionary(&self) -> Option<u32>

Indicates whether decompression failed due to requiring a dictionary.

The resulting integer is the Adler-32 checksum of the dictionary required.

impl DecompressError

pub fn message(&self) -> Option<&str>

Retrieve the implementation’s message about why the operation failed, if one exists.

Trait Implementations

impl Debug for DecompressError

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

Formats the value using the given formatter.

impl Display for DecompressError

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

Formats the value using the given formatter.

impl Error for DecompressError

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<DecompressError> for Error

fn from(data: DecompressError) -> Error

Converts to this type from the input type.
