Enum Error 

#[non_exhaustive]
pub enum Error {
    Key(String),
    Malformed(String),
    Missing(String),
    Unsupported(String),
    WrongKey(String),
    DigestMismatch,
    Invalid,
}

Why something could not be signed or verified.

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.

Key(String)

A key that cannot be read or made: a PEM, a Multikey, or a DID URL.

Malformed(String)

A signature, proof, header or URL that cannot be read.

Missing(String)

Something a signature covers that the request does not carry.

Unsupported(String)

An algorithm, cryptosuite or component this crate does not know.

WrongKey(String)

A key of one kind, offered for a signature or proof of another.

DigestMismatch

The body is not the one its digest describes.

Invalid

The signature or proof does not verify.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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 Eq for Error

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 PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
