Struct EmbedReport 

pub struct EmbedReport {
    pub pixels_modified: usize,
    pub payload_bytes: usize,
    pub effective_bpp: f32,
    pub image_dimensions: (u32, u32),
}

What one embedding operation did to the container.

A measurement of the finished stego image, not a receipt the receiver needs: none of these numbers travels with the payload, and the extraction path recomputes everything it needs from the image itself.

Fields

pixels_modified: usize

Positions whose carrier bit the trellis flipped, across both regions of the frame.

payload_bytes: usize

Ciphertext bytes embedded, tag included.

The compressed and encrypted size, not the length of the message the caller handed in: the plaintext length is not something the container carries, and reporting it here would suggest otherwise.

effective_bpp: f32

Bits embedded per pixel of the container, frame header included.

The figure the security of the scheme rests on. It is bounded by crate::stego::stc::MAX_BPP on each region of the frame, so it can never reach that ceiling over the image as a whole.

image_dimensions: (u32, u32)

Dimensions of the container as (width, height), in pixels.
