Enum webrender_api::TextureTarget

pub enum TextureTarget {
    Default,
    Array,
    Rect,
    External,
}

Specifies the type of texture target in driver terms.

Variants

Default

Standard texture. This maps to GL_TEXTURE_2D in OpenGL.

Array

Array texture. This maps to GL_TEXTURE_2D_ARRAY in OpenGL. See https://www.khronos.org/opengl/wiki/Array_Texture for background on Array textures.

Rect

Rectange texture. This maps to GL_TEXTURE_RECTANGLE in OpenGL. This is similar to a standard texture, with a few subtle differences (no mipmaps, non-power-of-two dimensions, different coordinate space) that make it useful for representing the kinds of textures we use in WebRender. See https://www.khronos.org/opengl/wiki/Rectangle_Texture for background on Rectangle textures.

External

External texture. This maps to GL_TEXTURE_EXTERNAL_OES in OpenGL, which is an extension. This is used for image formats that OpenGL doesn't understand, particularly YUV. See https://www.khronos.org/registry/OpenGL/extensions/OES/OES_EGL_image_external.txt

This method tests for !=.

impl Clone for TextureTarget

fn clone(&self) -> TextureTarget

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for TextureTarget

impl Eq for TextureTarget

impl Debug for TextureTarget

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

Formats the value using the given formatter.

impl Hash for TextureTarget

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where     H: Hasher,

Feeds a slice of this type into the given [Hasher].
