Struct glium::glutin::HeadlessRendererBuilder

pub struct HeadlessRendererBuilder<'a> {
    pub dimensions: (u32, u32),
    pub opengl: GlAttributes<&'a HeadlessContext>,
    // some fields omitted
}

Object that allows you to build headless contexts.

Fields

dimensions: (u32, u32)

The dimensions to use.

opengl: GlAttributes<&'a HeadlessContext>

The OpenGL attributes to build the context with.

Methods

impl<'a> HeadlessRendererBuilder<'a>

fn new(width: u32, height: u32) -> HeadlessRendererBuilder<'a>

Initializes a new HeadlessRendererBuilder with default values.

fn with_gl(self, request: GlRequest) -> HeadlessRendererBuilder<'a>

Sets how the backend should choose the OpenGL API and version.

fn with_gl_debug_flag(self, flag: bool) -> HeadlessRendererBuilder<'a>

Sets the debug flag for the OpenGL context.

The default value for this flag is cfg!(ndebug), which means that it's enabled when you run cargo build and disabled when you run cargo build --release.

fn with_gl_robustness(self, robustness: Robustness) -> HeadlessRendererBuilder<'a>

Sets the robustness of the OpenGL context. See the docs of Robustness.

fn build(self) -> Result<HeadlessContext, CreationError>

Builds the headless context.

Error should be very rare and only occur in case of permission denied, incompatible system, out of memory, etc.

fn build_strict(self) -> Result<HeadlessContext, CreationError>

Builds the headless context.

The context is build in a strict way. That means that if the backend couldn't give you what you requested, an Err will be returned.

Trait Implementations

impl<'a> DisplayBuild for HeadlessRendererBuilder<'a>

type Facade = GlutinFacade

The object that this DisplayBuild builds.

type Err = GliumCreationError<CreationError>

The type of error that initialization can return.

fn build_glium_debug(self, debug: DebugCallbackBehavior) -> Result<GlutinFacade, GliumCreationError<CreationError>>

Build a context and a facade to draw on it.

unsafe fn build_glium_unchecked_debug(self, debug: DebugCallbackBehavior) -> Result<GlutinFacade, GliumCreationError<CreationError>>

Build a context and a facade to draw on it

fn rebuild_glium(self, _: &GlutinFacade) -> Result<(), GliumCreationError<CreationError>>

Changes the settings of an existing facade.

fn build_glium(self) -> Result<Self::Facade, Self::Err> where Self: Sized

Build a context and a facade to draw on it.

unsafe fn build_glium_unchecked(self) -> Result<Self::Facade, Self::Err> where Self: Sized

Build a context and a facade to draw on it
