    GlThenGles {
        opengl_version: (u8, u8),
        opengles_version: (u8, u8),
    },
}

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 of GlThenGles

opengl_version: (u8, u8)

The version to use for OpenGL.

opengles_version: (u8, u8)

The version to use for OpenGL ES.

Methods

impl GlRequest[src]

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