Enum DpopError 

pub enum DpopError {
    UnexpectedOAuthError {
        error: String,
    },
    MissingDpopNonceHeader,
    TokenMintingFailed(Error),
    HeaderCreationFailed(InvalidHeaderValue),
    ResponseBodyParsingFailed(Error),
    ResponseBodyObjectParsingFailed,
}

Represents errors that can occur during DPoP (Demonstration of Proof-of-Possession) operations.

These errors occur when creating, validating, or using DPoP proofs for OAuth security.

Variants

UnexpectedOAuthError

Error when server returns an unexpected OAuth error.

This error occurs when the server returns an OAuth error other than the expected “use_dpop_nonce” error during DPoP nonce handling.

Fields

error: String

The unexpected error returned by the server

MissingDpopNonceHeader

Error when DPoP-Nonce header is missing from server response.

This error occurs when the server indicates that a DPoP nonce is required but fails to include the DPoP-Nonce header in the response.

TokenMintingFailed(Error)

Error when DPoP token minting fails.

This error occurs when the system fails to create (mint) a DPoP proof token, typically due to cryptographic key issues or claim validation problems.

HeaderCreationFailed(InvalidHeaderValue)

Error when HTTP header creation fails.

This error occurs when the DPoP proof token cannot be converted into a valid HTTP header value, typically due to invalid characters.

ResponseBodyParsingFailed(Error)

Error when response body JSON parsing fails.

This error occurs when the server response body cannot be properly parsed as JSON, typically due to malformed content or network issues.

ResponseBodyObjectParsingFailed

Error when response body is not a valid JSON object.

This error occurs when the server response body is valid JSON but not in the expected object format for OAuth error responses.

Trait Implementations

impl Debug for DpopError

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

Formats the value using the given formatter.

impl Display for DpopError

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

Formats the value using the given formatter.

impl Error for DpopError

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.
