Enum ProtocolError 

pub enum ProtocolError {
    Crypto(CryptoError),
    Serialization(Error),
    UnsupportedAlgorithm(String),
    MessageTypeMismatch,
    UnknownStatus(String),
}

Errors that can occur during protocol-level operations.

Variants

Crypto(CryptoError)

An underlying cryptographic operation failed.

Serialization(Error)

JSON serialization or deserialization failed.

UnsupportedAlgorithm(String)

The signature uses an algorithm other than Ed25519.

MessageTypeMismatch

The msg_type field does not match the body’s declared type.

UnknownStatus(String)

A status string could not be parsed into the expected enum.

Trait Implementations

impl Debug for ProtocolError

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

Formats the value using the given formatter.

impl Display for ProtocolError

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

Formats the value using the given formatter.

impl Error for ProtocolError

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<CryptoError> for ProtocolError

fn from(source: CryptoError) -> Self

Converts to this type from the input type.

impl From<Error> for ProtocolError

fn from(source: Error) -> Self

Converts to this type from the input type.
