Enum azul_core::app_resources::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

Trait Implementations

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 Debug for TextureTarget

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

Formats the value using the given formatter.

impl Eq for TextureTarget

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,

impl Ord for TextureTarget

fn cmp(&self, other: &TextureTarget) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<TextureTarget> for TextureTarget

fn eq(&self, other: &TextureTarget) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<TextureTarget> for TextureTarget

fn partial_cmp(&self, other: &TextureTarget) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
