Variants

UnknownError

UnsupportedExtension

An X11 extension was not supported by the server.

This corresponds to XCB_CONN_CLOSED_EXT_NOTSUPPORTED.

MaximumRequestLengthExceeded

A request larger than the maximum request length was sent.

This corresponds to XCB_CONN_CLOSED_REQ_LEN_EXCEED.

FDPassingFailed

File descriptor passing failed.

This corresponds to XCB_CONN_CLOSED_FDPASSING_FAILED.

ParseError

Error while parsing some data, see ParseError.

InsufficientMemory

Out of memory.

This is XCB_CONN_CLOSED_MEM_INSUFFICIENT.

IOError(Error)

An I/O error occurred on the connection.

Trait Implementations

impl Debug for ConnectionError

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

Formats the value using the given formatter.

impl Display for ConnectionError

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

Formats the value using the given formatter.

impl Error for ConnectionError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
