Struct librashader_runtime_gl::GLFramebuffer

pub struct GLFramebuffer { /* private fields */ }

A handle to an OpenGL FBO and its backing texture with format and size information.

Generally for use as render targets.

Implementations

impl GLFramebuffer

pub fn new_from_raw( texture: GLuint, fbo: GLuint, format: GLenum, size: Size<u32>, miplevels: u32 ) -> GLFramebuffer

Create a framebuffer from an already initialized texture and framebuffer.

The framebuffer will not be deleted when this struct is dropped.

Trait Implementations

impl Debug for GLFramebuffer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for GLFramebuffer

fn drop(&mut self)

Executes the destructor for this type.

Scale the framebuffer according to the provided parameters, returning the new size.
