Enum ProtocolError 

pub enum ProtocolError {
    Truncated,
    UnknownTag(u8),
    InvalidField(&'static str),
    MessageTooLarge(usize),
    Io(Error),
}

Errors that can occur during protocol encoding/decoding.

Variants

Truncated

Buffer does not contain a complete message.

UnknownTag(u8)

Unknown message type tag.

InvalidField(&'static str)

A field value is invalid (e.g., zero where a count is required, bad enum discriminant).

MessageTooLarge(usize)

Message exceeds maximum allowed frame size.

Io(Error)

Underlying I/O error.

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, f: &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<Error> for ProtocolError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<RequestFrameError> for ProtocolError

fn from(e: RequestFrameError) -> Self

For a codec whose error is ProtocolError, so its request encoder frames with ?. An oversized request is MessageTooLarge with the payload length; a buffer too small is Truncated, what this crate’s own encoders report for a buffer that cannot hold their output.
