Enum Error 

#[non_exhaustive]
pub enum Error {
    Signature(SignatureError),
    Token(TokenError),
    Key(String),
    Url(String),
    Discovery(String),
    Http(String),
    Invalid(String),
}

Everything else that can go wrong.

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.

Signature(SignatureError)

An HTTP signature did not verify.

Token(TokenError)

A token did not verify.

Key(String)

A key that cannot be read or used.

Url(String)

A URL that cannot be parsed, or that this client refuses to call.

Discovery(String)

A metadata document or key set that cannot be fetched, read or trusted.

Http(String)

A peer that could not be reached, failed, or answered with something unusable. Never a decision: a refusal is an answer, not an error.

Invalid(String)

A value that is not what the protocol requires.

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, __formatter: &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<SignatureError> for Error

fn from(source: SignatureError) -> Self

Converts to this type from the input type.

impl From<TokenError> for Error

fn from(source: TokenError) -> Self

Converts to this type from the input type.
