An error that occurred while connecting to an X11 server

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.

UnknownError

An unknown error occurred.

One situation were this error is used when libxcb indicates an error that does not match any of the defined error conditions. Thus, libxcb is violating its own API (or new error cases were defined, but are not yet handled by x11rb).

ParseError(ParseError)

Error while parsing some data, see ParseError.

InsufficientMemory

Out of memory.

This is XCB_CONN_CLOSED_MEM_INSUFFICIENT.

DisplayParsingError(DisplayParsingError)

Error during parsing of display string.

This is XCB_CONN_CLOSED_PARSE_ERR.

InvalidScreen

Server does not have a screen matching the display.

This is XCB_CONN_CLOSED_INVALID_SCREEN.

IoError(Error)

An I/O error occurred on the connection.

ZeroIdMask

Invalid ID mask provided by the server.

The value of resource_id_mask in the Setup provided by the server was zero.

SetupAuthenticate(SetupAuthenticate)

The server rejected the connection with a SetupAuthenticate message.

SetupFailed(SetupFailed)

The server rejected the connection with a SetupFailed message.

Incomplete

The client did not receive enough data from the server to complete the handshake.

Fields

expected: usize

The number of bytes that were expected.

received: usize

The number of bytes that were received.

Trait Implementations

impl Debug for ConnectError

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

Formats the value using the given formatter.

impl Display for ConnectError

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

Formats the value using the given formatter.

impl Error for ConnectError

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

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.
