Struct ComponentCoefficients 

pub struct ComponentCoefficients {
    pub id: u8,
    pub blocks: Vec<[i16; 64]>,
}

Quantized DCT coefficients for a single component (Y, Cb, or Cr).

Each element of blocks is one 8×8 DCT block, stored in the JPEG zigzag scan order:

• Index 0: DC coefficient (top-left of the frequency matrix).
• Indices 1–63: AC coefficients in zigzag order.

The values are the quantized coefficients exactly as they appear in the JPEG bitstream. They have not been dequantized; multiply by the quantization table to recover the pre-quantized DCT values.

Fields

id: u8

Component identifier as written in the JPEG SOF marker.

blocks: Vec<[i16; 64]>

All 8×8 blocks for this component, in raster scan order (left-to-right, top-to-bottom). Each block contains exactly 64 i16 values.
