}Object that allows you to build headless contexts.
Methods
impl HeadlessRendererBuilder
fn new(width: u32, height: u32) -> HeadlessRendererBuilder
Initializes a new HeadlessRendererBuilder with default values.
fn with_gl(self, request: GlRequest) -> HeadlessRendererBuilder
Sets how the backend should choose the OpenGL API and version.
fn with_gl_debug_flag(self, flag: bool) -> HeadlessRendererBuilder
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
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.
