Enum cogl::TextureComponents

#[non_exhaustive]
pub enum TextureComponents {
    A,
    Rg,
    Rgb,
    Rgba,
    Depth,
    // some variants omitted
}

See Texture::set_components.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

A

Only the alpha component

Rg

Red and green components. Note that this can only be used if the FeatureID::OglFeatureIdTextureRg feature is advertised.

Rgb

Red, green and blue components

Rgba

Red, green, blue and alpha components

Depth

Only a depth component

impl Ord for TextureComponents

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

This method returns an Ordering between self and other.

#[must_use]

pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]

pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]

pub fn clamp(self, min: Self, max: Self) -> Self
