Enum ProtocolError 

pub enum ProtocolError {
    EmptyFrame,
    UnknownMessageType(u8),
    InvalidLength {
        message_type: u8,
        expected: usize,
        actual: usize,
    },
    InvalidHandSide(u8),
}

Why a binary frame could not be decoded.

This is a small, copyable enum so downstream crates can match on the exact failure without string parsing.

Variants

EmptyFrame

The frame had no bytes, so it carried no type tag.

UnknownMessageType(u8)

The type tag did not correspond to any known message.

InvalidLength

The payload length did not match what the message type requires.

Fields

message_type: u8

expected: usize

actual: usize

InvalidHandSide(u8)

A hand frame carried a side byte that was neither right (0) nor left (1).

Trait Implementations

impl Clone for ProtocolError

fn clone(&self) -> ProtocolError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ProtocolError

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ProtocolError

impl Error for ProtocolError

Available on crate feature std only.

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 ProtocolError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
