Enum Error 

pub enum Error {
    NoEocd,
    Truncated,
    Zip64Unsupported,
    BadOffset,
    NonUtf8Name,
}

Variants

NoEocd

The end-of-central-directory record was not found.

Truncated

A structure extended past the buffer or a length was inconsistent.

Zip64Unsupported

A ZIP64 archive; not supported (rejected fail-closed).

BadOffset

A central directory entry pointed outside the archive.

NonUtf8Name

A ZIP entry name was not valid UTF-8.

Implementations

impl Error

pub fn code(&self) -> Option<&'static str>

The registered C2PA validation status code for this error, or None when the condition carries no status code.

Always None here, and deliberately so. Every variant is an archive parsing failure — the bytes are not a ZIP this crate can read — which happens before any manifest is located and so is not a validation outcome.

A ZIP-based asset is bound with a collection data hash, whose failures (assertion.collectionHash.mismatch and friends) belong to whoever computes the hash. This crate reports the byte ranges to hash and does not hash them, so those codes are not its to emit.

Every crate in this family exposes this method, so a dispatcher handling several embedding methods can ask the same question of any of them.

pub fn is_no_manifest_located(&self) -> bool

Whether this error means the asset carries no provenance at all.

Always false: an unreadable archive is not the same as a readable one carrying no manifest, which crate::read_manifest reports as Ok(None) rather than as an error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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>)
