Enum to store the various ways that operations can fail inside of the XCB implementations of penrose traits.

Variants

Connection(ConnError)

Unable to establish a connection to the X server

EmptyResponse(String)

A xcb query failed to return a value

Io(Error)

An IO Error was encountered

MissingProp(Atom, WinId)

A requested client property was empty

NoScreens

No screens were found

NonUtf8Prop(FromUtf8Error)

A string property on a window was invalid utf8

QueryFailed(&'static str)

An attempt to determine a certain property of the running system failed

Randr(String)

A query via the randr API was unsuccessful

Raw(String)

A generic error type for use in user code when needing to construct a simple XcbError.

Strum(ParseError)

Parsing a strum generated enum from a str failed.

UnknownScreen(usize, usize)

Screen data for an unknown screen was requested

XcbGeneric(Error<xcb_generic_error_t>)

Wrapper around low level XCB C API errors

Pango(String)

Error in using the pango API

UnintialisedSurface(WinId)

An attempt was made to fetch a surface for a client before creating it

UnknownMouseButton(u8)

A user specified mouse binding contained an invalid button

Trait Implementations

impl Debug for XcbError

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

Formats the value using the given formatter.

impl Display for XcbError

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

Formats the value using the given formatter.

impl Error for XcbError

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

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

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

🔬 This is a nightly-only experimental API. (backtrace #53487)

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

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
