Struct MipChain 

pub struct MipChain {
    pub base_width: u32,
    pub base_height: u32,
    pub channels: u32,
    pub levels: Vec<MipLevel>,
}

Describes the full mip chain for a texture.

Fields

base_width: u32

Base width of the texture (level 0).

base_height: u32

Base height of the texture (level 0).

channels: u32

Number of channels per pixel.

levels: Vec<MipLevel>

Individual mip level descriptors.

Implementations

impl MipChain

pub fn compute( base_width: u32, base_height: u32, channels: u32, max_levels: Option<u32>, ) -> Self

Compute the full mip chain for a texture with given dimensions.

Generates levels down to 1x1 unless max_levels limits the count.

pub fn level_count(&self) -> u32

Total number of mip levels in the chain.

pub fn total_size(&self) -> usize

Total size in bytes for the entire mip chain.

pub fn level(&self, index: u32) -> Option<&MipLevel>

Get a specific mip level by index.

pub fn is_single_level(&self) -> bool

Check whether the chain includes only a single level (no mips).

Trait Implementations

impl Clone for MipChain

fn clone(&self) -> MipChain

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MipChain

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

Formats the value using the given formatter.
