Enum ProtocolError 

pub enum ProtocolError {
    Io(Error),
    TooLarge(usize),
    Malformed(String),
}

帧编解码过程中的错误。

Variants

Io(Error)

底层 I/O 错误，包括 EOF 时帧不完整；对连接而言是致命的。

TooLarge(usize)

长度前缀超过上限（携带该上限）；对连接而言是致命的。

Malformed(String)

帧完整但内容非法（头 JSON 错误、未知 type、字段缺失或类型错误、载荷不一致），可跳过。

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<Error> for ProtocolError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ProtocolError> for Error

fn from(e: ProtocolError) -> Self

Converts to this type from the input type.
