Enum ProtocolError 

pub enum ProtocolError {
    UnexpectedVariant {
        found: &'static str,
        expected: &'static str,
    },
}

Structured-message protocol rejection.

This is distinct from transport failure (BackendError::CommunicationError) and from payload validation (BackendError::InvalidInput).

Variants

UnexpectedVariant

The decoded message variant is not the one this call accepts.

Fields

found: &'static str

Serde variant name that arrived (Ping, Spikes, …).

expected: &'static str

Serde variant name this call accepts.

Trait Implementations

impl Clone for ProtocolError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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 Eq for ProtocolError

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<ProtocolError> for BackendError

fn from(source: ProtocolError) -> Self

Converts to this type from the input type.

impl PartialEq for ProtocolError

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

Equality operator ==.

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

Inequality operator !=.
