Enum Error 

#[non_exhaustive]
pub enum Error {
    Http(HttpError),
    Server(ServerError),
    Parse(ParseError),
}

Errors returned by token requests (code exchange, refresh), re-exported from the underlying axum-security-oauth2 crate. Errors returned by OAuth2Client calls.

Configuration problems (missing endpoints, no HTTP backend) are caught by try_build as ConfigError; everything here can only happen at request time.

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.

Http(HttpError)

The HTTP request itself failed (connect, TLS, timeout, …).

Server(ServerError)

The server answered with a well-formed OAuth2 error body (RFC 6749 §5.2).

Parse(ParseError)

The server response could not be parsed.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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.
