Enum MessageError 

pub enum MessageError {
    NoKind,
    UnknownKind(String),
    Field {
        kind: String,
        field: &'static str,
    },
}

Why a payload is not the message it was read as.

Variants

NoKind

It has no kind string (and, for a string-shaped message, is not a string).

UnknownKind(String)

Its kind names no variant of the type.

Field

A field is missing, or holds a value of the wrong shape.

Fields

kind: String

field: &'static str

Trait Implementations

impl Clone for MessageError

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 MessageError

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

Formats the value using the given formatter.

impl Display for MessageError

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

Formats the value using the given formatter.

impl Eq for MessageError

impl Error for MessageError

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 PartialEq for MessageError

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

Equality operator ==.

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

Inequality operator !=.
