Enum ShellBackend 

pub enum ShellBackend {
    Wayland,
    X11,
    Win32,
    AppKit,
    Web,
    Headless,
}

Which implementation is behind the Shell trait.

For logs, error messages and bug reports. Shell behaviour must key off ShellCaps, never off this — that is the difference between a capability system and platform sniffing, and it is the same rule crcbl-hal’s BackendKind carries.

Variants

Wayland

Wayland, through libwayland-client and our own protocol layer (P0.5).

X11

X11, through libxcb and our own request/event layer (P0.6).

Win32

Win32, through hand-written extern "system" declarations (P5C).

AppKit

AppKit (P5C).

Web

A browser canvas, through the hand-rolled JS shim (P5).

Headless

HeadlessShell — no window system at all.

Implementations

impl ShellBackend

pub const fn as_str(self) -> &'static str

The lowercase name used in CRCBL_SHELL and in log lines.

pub fn from_name(name: &str) -> Option<Self>

Parses a CRCBL_SHELL value.

Accepts x11 and its common misspelling xcb, because the backend is built on libxcb and someone will type it.
