Struct ImageBuffer 

pub struct ImageBuffer { /* private fields */ }

A decoded, fully validated container image owned as a flat byte buffer.

The type deliberately does not implement Clone. Container images are several megabytes large, and an accidental copy would leave a second image in memory that no layer is responsible for wiping.

Trait Implementations

impl CoverSource for ImageBuffer

fn dimensions(&self) -> (u32, u32)

Image dimensions as (width, height), in pixels.

fn pixels(&self) -> &[u8]

Raw sample bytes in row-major order.

fn pixels_mut(&mut self) -> &mut [u8]

Mutable view of the raw sample bytes, used by the embedding layer.

fn color_space(&self) -> ColorSpace

Pixel layout of the underlying samples.

fn pixel_count(&self) -> usize

Total number of pixels in the image.

fn pixel_offset(&self, x: u32, y: u32) -> usize

Byte offset of the first sample of the pixel at (x, y).

impl Debug for ImageBuffer

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

Formats the value using the given formatter.

impl Zeroize for ImageBuffer

fn zeroize(&mut self)

Overwrites the sample buffer in place.

Written by hand rather than derived: only pixels holds data worth wiping, whereas the derive would also reset the dimensions, which are metadata a caller may still need while inspecting the wiped buffer.
