Enum FormatError 

pub enum FormatError {
    Truncated,
    NoEocd,
    BadSignature {
        what: &'static str,
        offset: u64,
    },

}

Structural defects in a ZIP container. Each variant preserves the offending value/location (CLAUDE.md “Show the unrecognized value”).

Variants

Truncated

A header read ran past the available bytes.

NoEocd

No End Of Central Directory record was found.

BadSignature

A record did not start with its expected signature.

Fields

what: &'static str

Which record was expected.

offset: u64

Where it was looked for.

Zip64Unsupported

The archive uses Zip64 features not yet implemented.

Zip64Inconsistent

A 0xFFFFFFFF sentinel was present but the Zip64 record/extra field that should carry the real value is missing or malformed.

CentralDirOutOfRange

The central directory offset/size fall outside the file.

Fields

cd_offset: u64

Declared central-directory offset.

cd_size: u64

Declared central-directory size.

TooManyEntries(usize)

The EOCD declared an entry count beyond the safety ceiling.

Trait Implementations

impl Debug for FormatError

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

Formats the value using the given formatter.

impl Display for FormatError

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

Formats the value using the given formatter.

impl Error for FormatError

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<FormatError> for ZipCoreError

fn from(source: FormatError) -> Self

Converts to this type from the input type.
