Enum ImgFormat 

pub enum ImgFormat {
    R(u8),
    RG(u8),
    RGB(u8),
    RGBA(u8),
}

Texture image format, encoding channel count and bit depth.

Each variant carries the per-channel bit depth (e.g. RGBA(8) = 4×8-bit).

Variants

R(u8)

RG(u8)

RGB(u8)

RGBA(u8)

Implementations

impl ImgFormat

pub fn channels(&self) -> u8

Number of color channels (1–4).

pub fn bit_depth(&self) -> u8

Bits per channel.

pub fn pixel_size(&self) -> u8

Total bytes per pixel (channels × bit_depth / 8).

pub fn from(channels: u8, bit_depth: u8) -> ImgFormat

Construct from channel count and bit depth.

Channels ≥ 4 produce RGBA. Unknown channels default to RGBA.

Trait Implementations

impl Clone for ImgFormat

fn clone(&self) -> ImgFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ImgFormat

impl Debug for ImgFormat

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

Formats the value using the given formatter.

impl PartialEq for ImgFormat

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