Enum Error 

#[non_exhaustive]
pub enum Error {
    Server {
        code: String,
        message: String,
    },
    Protocol(String),
    Io(Error),
    Timeout(String),
    TooLarge(String),
    TooManyEntries(String),
    Partial {
        written: usize,
        source: Box<Error>,
    },
}

Errors returned by the client. New variants can be added, so a match needs a wildcard arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Server

The server answered with an error frame. code is a POSIX name such as ENOENT.

Fields

code: String

message: String

Protocol(String)

The peer broke the frame or message contract.

Io(Error)

The socket failed.

Timeout(String)

A call did not finish within Options::call_timeout. On a pipelining connection only this call fails and the late reply is dropped. Otherwise the connection was dropped, so a late reply cannot reach another call, and its open files and watches are gone. The code is DEADLINE_EXCEEDED and the io::ErrorKind is TimedOut.

TooLarge(String)

A request is larger than the frame limits. Nothing was sent and the connection is intact.

TooManyEntries(String)

A directory helper hit its bound: read_dir_all found more entries than its limit, or walk queued more pending directories than its limit. The message names the limit.

Partial

A write that covers more than one frame failed after written bytes were stored. source is the failure. code and the io::ErrorKind come from source.

Fields

written: usize

source: Box<Error>

Implementations

impl Error

pub fn code(&self) -> Option<&str>

Server error code, if this is a server error. A timeout has the code DEADLINE_EXCEEDED. A partial write has the code of its cause.

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, f: &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(e: Error) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Error

Converts to this type from the input type.
