Struct piet_glow::GlContext

pub struct GlContext<H: HasContext + ?Sized> { /* private fields */ }

A wrapper around a glow context with cached information.

Implementations

impl<H: HasContext + ?Sized> GlContext<H>

pub unsafe fn new(context: H) -> Result<Self, Pierror>where H: Sized,

Create a new GlContext from a glow context.

Safety

The context must be current while calling new, and the context must be current when this type is dropped.

pub fn context(&self) -> &H

Get a reference to the underlying glow context.

pub unsafe fn render_context( &mut self, width: u32, height: u32 ) -> RenderContext<'_, H>

Get a render context.

Safety

The context must be current while calling this method, as well as any of the piet::RenderContext methods.
