Struct screen_13::EventLoopBuilder

pub struct EventLoopBuilder { /* private fields */ }

Builder for EventLoop.

Implementations

impl EventLoopBuilder

pub fn available_monitors(&self) -> impl Iterator<Item = MonitorHandle>

Returns the list of all the monitors available on the system.

pub fn configure<ConfigureFn>(self, configure_fn: ConfigureFn) -> Selfwhere
    ConfigureFn: FnOnce(DriverConfigBuilder) -> DriverConfigBuilder,

Provides a closure which configures the DriverConfig instance.

pub fn desired_swapchain_image_count(
    self,
    desired_swapchain_image_count: u32
) -> Self

A request to the driver to use a certain number of swapchain images.

More images introduces more display lag, but smoother animation.

pub fn sync_display(self, sync_display: bool) -> Self

Set to true to enable vsync in exclusive fullscreen video modes.

pub fn fullscreen_mode(self, mode: FullscreenMode) -> Self

Sets up fullscreen mode using a conveience function. There are additional options offered by winit which can be accessed using the with function.

pub fn debug(self, debug: bool) -> Self

Enables Vulkan graphics debugging layers.

NOTE: Any valdation warnings or errors will cause the current thread to park itself after describing the error using the log crate. This makes it easy to attach a debugger and see what is causing the issue directly.

pub fn primary_monitor(&self) -> Option<MonitorHandle>

Returns the primary monitor of the system.

Returns None if it can’t identify any monitor as a primary one.

Platform-specific

Wayland: Always returns None.

pub fn ray_tracing(self, ray_tracing: bool) -> Self

Pass true to this method to enable hardware ray tracing, if supported.

pub fn resolver_pool(self, pool: Box<dyn ResolverPool>) -> Self

Allows for specification of a custom pool implementation.

This pool will hold leases for Vulkan objects needed by Display.

pub fn window<WindowFn>(self, window_fn: WindowFn) -> Selfwhere
    WindowFn: FnOnce(WindowBuilder) -> WindowBuilder,

Allows deeper customization of the window, if needed.

pub fn window_mode(self) -> Self

Sets up “windowed” mode, which is the opposite of fullscreen.

impl EventLoopBuilder

pub fn build(self) -> Result<EventLoop, DriverError>

Builds a new EventLoop.

Trait Implementations

impl Debug for EventLoopBuilder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for EventLoopBuilder

fn default() -> Self

Returns the “default value” for a type.
