Struct Backends 

pub struct Backends { /* private fields */ }

Configuration for all backends in a WaterUI project.

[backend] in Water.toml

Implementations

impl Backends

pub const fn is_empty(&self) -> bool

Check if no backends are configured.

pub fn configures_backend_projects(&self) -> bool

Whether any backend-project scaffolding is configured.

[backends.esp32] is deliberately excluded: it carries device configuration — chip, panel geometry, bundled fonts — that only the app author can know, while the other entries describe backend projects that playground mode delegates to the CLI. A backend_path entry is excluded for the opposite reason: it only selects where the CLI finds a backend’s runtime source and configures no project.

pub fn path(&self) -> &Path

Get the base path for backends, relative to project root.

pub fn set_path(&mut self, path: impl Into<String>)

Set the base path for backends.

pub const fn android(&self) -> Option<&AndroidBackend>

Get the Android backend configuration, if any.

pub const fn apple(&self) -> Option<&AppleBackend>

Get the Apple backend configuration, if any.

pub fn set_apple(&mut self, backend: AppleBackend)

Set the Apple backend configuration.

pub fn clear_apple(&mut self)

Remove Apple backend configuration.

pub fn set_android(&mut self, backend: AndroidBackend)

Set the Android backend configuration.

pub fn clear_android(&mut self)

Remove Android backend configuration.

pub const fn gtk4(&self) -> Option<&Gtk4Backend>

Get the GTK4 backend configuration, if any.

pub fn set_gtk4(&mut self, backend: Gtk4Backend)

Set the GTK4 backend configuration.

pub fn clear_gtk4(&mut self)

Remove GTK4 backend configuration.

pub const fn hydrolysis(&self) -> Option<&HydrolysisBackend>

Get the hydrolysis backend configuration, if any.

pub fn set_hydrolysis(&mut self, backend: HydrolysisBackend)

Set the hydrolysis backend configuration.

pub fn clear_hydrolysis(&mut self)

Remove hydrolysis backend configuration.

pub const fn winui(&self) -> Option<&WinUiBackend>

Get the WinUI backend configuration, if any.

pub fn set_winui(&mut self, backend: WinUiBackend)

Set the WinUI backend configuration.

pub fn clear_winui(&mut self)

Remove WinUI backend configuration.

pub const fn esp32(&self) -> Option<&Esp32Backend>

Get the ESP32 backend configuration, if any.

pub fn set_esp32(&mut self, backend: Esp32Backend)

Set the ESP32 backend configuration.

pub fn clear_esp32(&mut self)

Remove ESP32 backend configuration.
