    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
