Enum ConnError 

#[non_exhaustive]
pub enum ConnError {
    NoDisplay,
    NoLogname,
    Io(PathBuf, Error),
    BadScreen(i32),
    ServerNotFound,
    X11(Error),
}

Error during establishing connection to the Sawfish 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.

NoDisplay

No display specified and DISPLAY environment variable not set.

NoLogname

LOGNAME environment variable not set.

This is relevant when connecting to Unix socket since without the login name socket name cannot be determined.

Io(PathBuf, Error)

An I/O error during establishing of the connection (e.g. Unix socket does not exist or user lacks permissions to access it).

BadScreen(i32)

Available on crate feature experimental-xcb only.

Invalid X11 display screen number.

ServerNotFound

Available on crate feature experimental-xcb only.

No Sawfish server found on display.

X11(Error)

Available on crate feature experimental-xcb only.

An X11 error during establishing of the connection.

Trait Implementations

impl Debug for ConnError

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

Formats the value using the given formatter.

impl Display for ConnError

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

Formats the value using the given formatter.

impl Error for ConnError

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
