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))`

Tuple Fields

0: Api

1: (u8, u8)

Request a specific version of a specific API.

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

`GlThenGles`

Fields

opengl_version: (u8, u8)

The version to use for OpenGL.

opengles_version: (u8, u8)

The version to use for OpenGL ES.

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.

Implementations

impl GlRequest

pub fn to_gl_version(&self) -> Option<(u8, u8 )>
