Enum PlatformError 

pub enum PlatformError {
    Connect,
    Registry,
    MissingCompositor,
    MissingLayerShell,
    ConnectionLost,
    NoGpu,
}

Why the platform layer could not start or continue.

These are ordinary environmental conditions (no Wayland session, a compositor without layer-shell such as GNOME, a dropped connection, no GPU to draw a surface with) — they are reported instead of panicking the process.

Variants

Connect

Could not connect to a Wayland display (no session / wrong env).

Registry

Wayland registry initialization failed.

MissingCompositor

The compositor does not advertise wl_compositor.

MissingLayerShell

The compositor does not support zwlr_layer_shell_v1 (e.g. GNOME).

ConnectionLost

The Wayland connection failed while the app was running.

NoGpu

No Vulkan adapter could draw the surface that asked for one.

impl Eq for PlatformError

impl Error for PlatformError

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

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.

impl PartialEq for PlatformError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
