Enum Error 

pub enum Error {
    Json(Error),
    Io(Error),
    FramingError,
    MismatchedCount {
        expected: usize,
        found: usize,
    },
    SystemCall(String),
    ConnectionClosed,
    InvalidMessage(String),
}

Variants

Json(Error)

JSON serialization or deserialization failed.

Io(Error)

An I/O error occurred.

FramingError

The message contained invalid JSON.

MismatchedCount

The fds field in the message doesn’t match the number of received file descriptors.

Fields

expected: usize

Number of file descriptors specified in the fds field.

found: usize

Number of file descriptors actually available.

SystemCall(String)

ConnectionClosed

The connection was closed by the peer.

InvalidMessage(String)

The message format was invalid.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self
