Enum wayland_client::ConnectError

pub enum ConnectError {
    NoWaylandLib,
    XdgRuntimeDirNotSet,
    NoCompositorListening,
    InvalidName,
    InvalidFd,
}

Enum representing the possible reasons why connecting to the wayland server failed

Variants

NoWaylandLib

The library was compiled with the dlopen feature, and the libwayland-client.so library could not be found at runtime

XdgRuntimeDirNotSet

The XDG_RUNTIME_DIR variable is not set while it should be

NoCompositorListening

Any needed library was found, but the listening socket of the server was not.

Most of the time, this means that the program was not started from a wayland session.

InvalidName

The provided socket name is invalid

InvalidFd

The FD provided in WAYLAND_SOCKET was invalid

Trait Implementations

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<(), Error>

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 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
