Enum Error 

pub enum Error {
    NotFound,
    InvalidRecord(String),
    Io(Error),
}

Variants

NotFound

No C2PA manifest record was present in the archive.

InvalidRecord(String)

A WARC record was structurally malformed.

Io(Error)

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. Error::NotFound means the archive carries no provenance, which is not a failure; the other two are archive-parsing and I/O problems that occur before any manifest is located. The specification defines no WARC-specific codes.

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 archive carries no provenance at all, as opposed to provenance that was found and rejected.

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.
