Implementations

impl TextureFormat

pub const fn is_compressed(self) -> bool

Returns whether this is a block-compressed format.

pub const fn bytes_per_pixel(self) -> Option<usize>

Returns bytes per texel for uncompressed formats.

pub const fn block_dimensions(self) -> Option<(u32, u32)>

Returns (width, height) for compressed blocks.

pub const fn bytes_per_block(self) -> Option<usize>

Returns bytes per compressed block.

pub const fn mip_dimensions(width: u32, height: u32, level: u32) -> (u32, u32)

Returns the dimensions of a mip level.

pub fn expected_2d_len( self, width: u32, height: u32, ) -> Result<usize, ValidationError>

Returns the expected byte length for a 2D texture level.

pub fn expected_3d_len( self, width: u32, height: u32, depth: u32, ) -> Result<usize, ValidationError>

Returns the expected byte length for a 3D texture level.

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 Hash for TextureFormat

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 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.
