Enum TextureFormat 

pub enum TextureFormat {
    Bc1RgbUnorm,
    Bc4RUnorm,
}

Target block-compressed texture format produced by TextureCompressor.

Variants

Bc1RgbUnorm

BC1 (DXT1) RGB opaque compression.

• Input: RGBA8 — width × height × 4 bytes.
• Output: 8 bytes per 4×4 block → (width/4) × (height/4) × 8 bytes.
• Compression ratio: 6:1 (vs. RGBA8).

Bc4RUnorm

BC4 single-channel (ATI1 / RGTC1) compression.

• Input: R8 — width × height bytes.
• Output: 8 bytes per 4×4 block → (width/4) × (height/4) × 8 bytes.
• Compression ratio: 2:1 (vs. R8).

Trait Implementations

impl Clone for TextureFormat

fn clone(&self) -> TextureFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TextureFormat

impl Debug for TextureFormat

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

Formats the value using the given formatter.

impl Eq for TextureFormat

impl PartialEq for TextureFormat

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
