Enum CompressionVariant 

pub enum CompressionVariant {
    BC7(BC7Settings),
}

Block compression variants supported by this crate.

Variants

BC7(BC7Settings)

BC7 compression with smooth alpha (RGBA)

Implementations

impl CompressionVariant

pub const fn bytes_per_row(self, width: u32) -> u32

Returns the bytes per row for the given width.

The width is used to calculate how many blocks are needed per row, which is then multiplied by the block size. Width is rounded up to the nearest multiple of 4.

pub const fn blocks_byte_size(self, width: u32, height: u32) -> usize

Returns the byte size required for storing compressed blocks for the given dimensions.

The size is calculated based on the block compression format and rounded up dimensions. Width and height are rounded up to the nearest multiple of 4.

Trait Implementations

impl Clone for CompressionVariant

fn clone(&self) -> CompressionVariant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionVariant

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

Formats the value using the given formatter.

impl Hash for CompressionVariant

Available on crate features bc15 or bc6h or bc7 only.

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CompressionVariant

Available on crate features bc15 or bc6h or bc7 only.

fn eq(&self, other: &Self) -> 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.

impl Copy for CompressionVariant

impl Eq for CompressionVariant
