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 command_buffer_count(self, cmd_buf_count: usize) -> Self

Specifies the number of in-flight command buffers, which should be greater than or equal to the desired swapchain image count.

More command buffers mean less time waiting for previously submitted frames to complete, but more memory in use.

Generally a value of one or two greater than desired image count produces the smoothest animation.

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. In addition, decorations are set to false and maximized is set to true.

Note

There are additional options offered by winit which can be accessed using the window 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.

Note

There are additional options offered by winit which can be accessed using the window function.

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.
