pub enum GlRequest {
    Latest,
    Specific(Api, (u8, u8)),

Expand description

Describes the OpenGL API and version that are being requested when a context is created.

Variants§

§

Latest

Request the latest version of the “best” API of this platform.

On desktop, will try OpenGL.

§

Specific(Api, (u8, u8))

Request a specific version of a specific API.

Example: GlRequest::Specific(Api::OpenGl, (3, 3)).

§

GlThenGles

If OpenGL is available, create an OpenGL context with the specified opengl_version. Else if OpenGL ES or WebGL is available, create a context with the specified opengles_version.

Fields

§opengl_version: (u8, u8)

The version to use for OpenGL.

§opengles_version: (u8, u8)

The version to use for OpenGL ES.
