Struct Metadata 

#[non_exhaustive]
pub struct Metadata {
    pub width: u32,
    pub height: u32,
    pub format: Format,
    pub pixel: PixelFormat,
}

Header-only facts about an image.

Answering this must not decode pixels (SPEC §Guarantees 3).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

width: u32

Width in pixels.

height: u32

Height in pixels.

format: Format

The container format the image was read from.

pixel: PixelFormat

The pixel format the decoder will produce.
