Struct HeadlessContext 

pub struct HeadlessContext { /* private fields */ }

Available on crate feature headless and non-WebAssembly only.

A headless graphics context, ie. a graphics context that is not associated with any window. For a graphics context associated with a window, see WindowedContext. Can only be created on native, not on web.

Implementations

impl HeadlessContext

pub fn new() -> Result<Self, HeadlessError>

Creates a new headless graphics context.

Methods from Deref<Target = Context>

pub fn set_scissor(&self, scissor_box: ScissorBox)

Set the scissor test for this context (see ScissorBox).

pub fn set_viewport(&self, viewport: Viewport)

Set the viewport for this context (See Viewport).

pub fn set_cull(&self, cull: Cull)

Set the face culling for this context (see Cull).

pub fn set_write_mask(&self, write_mask: WriteMask)

Set the write mask for this context (see WriteMask).

pub fn set_depth_test(&self, depth_test: DepthTest)

Set the depth test for this context (see DepthTest).

pub fn set_blend(&self, blend: Blend)

Set the blend state for this context (see Blend).

pub fn set_render_states(&self, render_states: RenderStates)

Set the render states for this context (see RenderStates).

pub fn error_check(&self) -> Result<(), CoreError>

Returns an error if an GPU-side error has happened while rendering which can be used to check for errors while developing. Can also be used in production to handle unexpected rendering errors, but do not call it too often to avoid performance problems.
